Variance is a statistical measure of the dispersion of returns from asset price movements. It’s calculated by subtracting the average return from an investment and dividing it by its standard deviation, which gives us a number between 0 (if all returns are equal) and 1.
High variability is a sign of high risk. Low variance means that the asset’s price follows a predictable pattern. Read more in detail here: what does low variance mean.
When the variance is 0, it means that all of the data values are the same. All variances that are not zero are positive. A low variance means that the data points are often near to the mean and to one another. A large variance shows that the data points are far apart from the mean and one another.
Also, do you like a lot or a little variation?
Low variance is linked to lower risk and poorer returns. Limited variance stocks are suitable for cautious investors with a low risk tolerance, whereas high variance stocks are good for aggressive investors who are less risk averse. Variance is a metric for determining how risky an investment is.
The issue then becomes, what does a standard deviation of 15 imply? A norm group with an average score of 100 and a standard deviation of 15 is used to determine an IQ test result. The standard deviation, in this context of IQ scores, is a measure of dispersion. A standard deviation of 15 indicates that 68 percent of the norm group scored in the range of 85 (100 – 15) to 115 (100 + 15).
Second, what constitutes a good variation?
As a rule of thumb, a CV >= 1 indicates a relatively high variation, while a CV < 1 can be considered low. This means that distributions with a coefficient of variation higher than 1 are considered to be high variance whereas those with a CV lower than 1 are considered to be low-variance.
What percentage of standard deviation is a good one?
If a data distribution is roughly normal, approximately 68 percent of the data values are within one standard deviation of the mean (mathematically, where is the arithmetic mean), approximately 95 percent are within two standard deviations ( 2), and approximately 99.7% are within three standard deviations ( 3).
Answers to Related Questions
What does a five-standard-deviation standard deviation mean?
A low standard deviation indicates that the majority of the data points are close to the mean. A large standard deviation indicates that the data is more dispersed. In most cases, the declared margin of error is double the standard deviation.
Is it beneficial to have a low standard deviation?
The data points tend to be relatively near to the mean when the standard deviation is low. A big standard deviation shows that the data points span a wide range of values. Because it returns to the data set’s original units of measure, standard deviation is a common measure of variability.
What’s the connection between the mean and the standard deviation?
According to Investopedia. 7th of May, 2019 update The standard deviation (SD) is a measure of how much a subject set of data deviates from the mean, while the standard error of the mean (SEM) is a measure of how far the sample mean deviates from the real population mean.
What is the definition of a considerable standard deviation?
“A substantial standard deviation indicates that there is a 95% possibility that the difference is the result of discrimination.” The more standard deviations there are, the less probable it is that the discrepancy is due to chance.
What is the significance of variance?
It is critical for visualizing and comprehending the material under consideration. In some ways, statistics were established to express data in two or three numbers. The variance is a measure of how scattered or spread out the data set is, which is something the “average” (mean or median) isn’t meant to achieve.
Is a larger or smaller standard deviation preferable?
The standard deviation is a mathematical tool that may be used to determine how far data differ from the mean. A large standard deviation indicates that the data is dispersed (unreliable), whereas a low standard deviation indicates that the data is tightly grouped around the mean (more reliable).
What is variance, exactly?
The variance is a measure of how widely a collection of integers is spread out in probability theory and statistics. The variance of a random variable defines how much it deviates from its predicted value. The average of the squares of the deviations between the individual (observed) and the predicted value is the variance.
Is it possible for the variance to be negative?
You’ve made a mistake if your variance is negative.
Variance can never be negative due to its computation and mathematical definition, since it is the average squared variation from the mean, and anything squared is never negative. It’s also impossible for the average of non-negative values to be negative.
What does the term “variance” signify in statistics?
The expectation of a random variable’s squared departure from its mean is known as variance in probability theory and statistics. Informally, it calculates the distance between a collection of (random) integers and their average value.
What does variance reveal about a collection of data?
The variance (2) indicates how much each value in the data set deviates from the mean. Subtract the data’s mean from each value. This offers you a measure of how much each number deviates from the mean. Add all of the squares together and square each of these distances (such that they are all positive numbers).
What does a one-standard-deviation standard deviation mean?
Data within one standard deviation of the mean may be regarded quite typical and anticipated, depending on the distribution. It essentially informs you that the data is neither excessively high nor excessively low. Take a look at the normal distribution as an example (this is not the only possible distribution though).
What is a reasonable standard deviation?
When a sample is taken from a larger population, the sample’s average (or mean) will be a close approximation of the overall mean. As a result, 68% of all sample means will be within one standard deviation of the population mean (and 95 percent within two standard errors).
What criteria do you use to determine if standard error is significant?
The standard error of a coefficient estimate indicates how much variability “surrounds” it. If a coefficient is not zero, it is significant. To generate a 95 percent confidence range for a coefficient estimate, the conventional rule of thumb is to go two standard deviations above and below the estimate.
Is variation a good thing or a negative one?
In and of itself, variance is neither beneficial nor bad for investors. However, a stock with a large volatility is connected with a greater risk as well as a higher return. Low variance is linked to lower risk and poorer returns.
Is it possible for the standard deviation to be higher than the mean?
A lower standard deviation suggests that the data is more tightly packed around the mean. A bigger one suggests that the data is more dispersed. The standard deviation is bigger than the mean in the first scenario. It is smaller in the second scenario.
Instant Money Transfers: How to Speed Up Your Financial Transactions?
People today are no longer limited to using traditional banking methods and payment options like cash or checks for their financial transactions. With digital payment options becoming increasingly popular, money transfers have become easier. However, while these solutions offer convenience, they only sometimes guarantee a speedy transaction of funds from one party to another. If you need an instant transfer solution that allows you to move your funds without any hassles quickly, keep reading. Here are some tips to help you get started with an instant money transfer:
Find a Trustworthy Money Transfer Provider
Finding a trustworthy money transfer provider is paramount in ensuring your money’s safe and efficient transfer. Start by researching different providers, particularly their reputation, customer reviews, and transaction security protocols. The team at Paysend can help you send money to the Philippines from the USA in just a matter of seconds. A reliable provider should have a robust security framework to guard against fraud and hacking attempts. Additionally, consider the speed of their service, the fees they charge, and the exchange rates they offer.
Some providers may offer attractive transfer rates but compensate with hidden charges, so read the fine print. Customer service is another important factor; a good provider will have a responsive and knowledgeable support team to promptly address any issues or concerns. Regulatory compliance is also crucial – ensure the appropriate financial authorities regulate the provider. Remember, a trustworthy provider prioritizes the security and satisfaction of its customers above all else.
Select Your Preferred Payment Method
Choosing your preferred payment method is a critical step in instant money transfers. Several payment methods are available, and the best choice often depends on one’s circumstances and preferences. The most common payment options include bank transfers, debit or credit cards, and digital wallets. Bank transfers, while reliable, may provide a different speed than some users require. Debit or credit card payments are typically faster but may carry higher fees.
Digital wallets like PayPal or Apple Pay offer speed and convenience, allowing you to transfer funds digitally without requiring bank account information. The factor to consider here is not just the convenience of the payment method but also its transaction speed, security, and associated charges. Always select a payment method that suits your needs regarding these factors.
Sign Up for an Account
Once you have selected the ideal payment method and provider, it is time to sign up for an account. Most providers will require personal information such as your name, address, email ID, and phone number, so make sure the details you provided are accurate. You might also be asked to supply additional documents, such as identification proof and bank statements, to verify your identity.
Sometimes, you may need to link your bank account with the transfer provider’s platform; read through their documentation carefully to understand what steps you need to take. Once the registration process is complete, you can access and use the money transfer service for quick transfers.
Initiate the Money Transfer
Most providers will require you to register on their platform with valid ID documents before proceeding. Enter all the necessary details correctly and accurately, including recipient information and account numbers. Additionally, make sure that you double-check the amount of money being transferred and the associated fees.
Confirm everything is correct before hitting ‘Send’ to avoid costly mistakes or delays in transfer processing. You should receive an email or text message confirming the transfer with your transaction details, including the recipient’s account information and a tracking number. You can use this tracking number to monitor the progress of your money transfer.
Complete the Money Transfer Process
This usually requires providing basic information such as the recipient’s name, address, and contact details. Depending on your provider, you may also need to specify what currency you’re sending and offer additional security authentication. Once this is done, enter the amount you wish to transfer, verify the transaction details, and approve it. After that, your money should be on its way to the recipient’s account immediately.
Some providers offer extra features such as tracking services or reminders for upcoming transfers for added security and convenience. These features can come in handy when sending payments regularly or tracking the status of a transaction. Additionally, look out for any special offers, discounts, or rewards available to loyal customers. Many money transfer providers offer these incentives as a way of showing appreciation and encouraging loyalty among their customers.
Monitor the Status of Your Transfer
Most providers will allow you to monitor the progress of your transfer in real time. Some may even send notifications via email or text message when the money reaches its destination. If you sense any delays, contact customer support for assistance. Money transfers can take a few minutes to several hours, depending on the selected payment method and recipient country.
Finally, always save all records related to your money transfers, including emails and receipts. If there are any discrepancies or disputes, you can refer to these documents for clarification. With the help of a reliable provider and modern payment methods like digital wallets, you can now easily make instant money transfers. So get started today and experience the convenience of instant money transfer services.
Receive and Verify the Transaction
Once the money has been transferred, you or the recipient should receive a notification of completion. At this point, ensuring the transaction was successful, and all details were correct is important. For security purposes, some providers may ask for additional verification from either party to avoid fraud and other malicious activities. This process could include providing a digital signature or proof of identity.
Once the verification is complete, the funds should be available in the recipient’s account almost immediately. If you have any concerns, contact customer support to get assistance or help resolve any issues. Remember that reliable providers prioritize customer satisfaction and security above all else. With these steps, you can now easily and safely transfer money with instant money transfer services.
Nowadays, it’s more important than ever to employ secure digital payment methods in your daily financial transactions. That’s why researching which providers offer the best services regarding speed, security, transaction fees, and customer support pays off. With the right provider, you can have peace of mind knowing that your money transfers will be conducted instantaneously and securely.
The Ins and Outs of Getting a Loan With Bad Credit
If financial difficulties or uninformed decisions have left you with bad credit, you may not know where to turn for a loan. While borrowing money with a low credit score may take additional research or work, it’s likely still within your reach.
Many lenders offer bad credit loans for people who need extra cash but may not have the best credit background. Applying for a loan with bad credit may feel intimidating, but the following considerations could make the process easier.
Start by Checking Your Credit
Before you begin shopping for loans, check your credit report. Some creditors require specific scores for each loan product, even those designed for bad credit, so knowing your score saves you time.
It’s also important to check your credit report for errors that may drag your score down and limit your loan options. You can access this information from Equifax and TransUnion for free online.
Compare Your Options
While a lower credit score likely disqualifies you from some personal loans, you may still have many options. Some lenders offer loans specifically for people with low credit scores who struggle to qualify for other options.
Bad credit loans may require a deposit or other fees, have higher interest rates than other loans, or include income requirements. However, they may also offer a wide range of payment terms and options like online portals that make managing your loan easier. With some research, you could find the right fit for your circumstances.
Whenever possible, take advantage of loan prequalification. Many lenders allow you to check your potential eligibility for a loan by providing personal and financial information. They use that to run a soft credit check, which doesn’t affect your credit score. If you pre-qualify, they’ll provide information about possible rates and terms. You could complete prequalification forms for multiple loans to help you find your best option.
Improve Your Application
Some financial decisions improve your loan eligibility. A friend or family member with better credit may agree to co-sign your loan. In that case, their financial information influences your eligibility for a loan.
Cosigners take on substantial risk. If you fail to repay your loan, your cosigner becomes responsible. Likewise, issues with the loan could hurt their credit score and put a strain on your interpersonal relationship.
If multiple lenders have declined your applications for unsecured loans, consider a secured loan instead. Secured loans require collateral, like a deposit, car, or other property. If borrowers don’t repay their loans, lenders may seize the collateral. Lending institutions don’t take on as much risk with secured loans as unsecured loans so they may have more lenient credit requirements for borrowers.
Unfortunately, fraudulent lenders often exploit consumers who have limited loan options. Before providing a lender with any personal or financial information, ensure they’re legitimate. Otherwise, you risk having your identity stolen or paying fees for a loan you never receive.
Be wary of anyone offering guaranteed approval or soliciting your business via cold calls. Always verify loan servicers’ contact information and check their reviews on trusted third-party websites.
The Bottom Line
If you have bad credit, you could still qualify for a personal loan. Remember to check your credit score, investigate your options, and confirm a lender’s legitimacy before applying. If you still struggle to qualify, you may need a cosigner or collateral to boost your application.
By taking some extra steps, you can make getting a loan easier and safer.
Four Ways to Save on Fuel in 2023
From increasing energy bills to price hikes at online stores and supermarkets, all individuals globally feel the need to make their money to go further and do more. And there has never been a perfect time to know how to save more on fuel than now.
From getting fuel cards with great deals and driving more efficiently to using telematics and keeping your vehicle in good condition, here are different ways to save money on fuel.
Get a Fuel Card
A fuel card can provide you with more than the ability to purchase fuel from a good station. With a fuel card, you can control your business’s fuel spend by getting discounts on fuel pump rates, setting spending limitations, and increasing your cash flow – all enabling you to save a significant amount of money.
Fuel cards allow savings on fuel, which means that the price you pay is always less compared to the one indicated on the fuel pump machine. With numerous fuel cards available out there, find the right partner with excellent deals.
Use Telematics/Advanced Route Planning
Digital telematics solutions come with real-time GPS tracking as well as remote automobile diagnostics helping individuals and company owners to thoughtfully plan the most efficient routes depending on different data points. A high-quality telematics solution also integrates with route optimisation systems to plan the most efficient routes and offer turn-by-turn directions and navigations.
Well-planned routes allow automobiles to get from point C to D efficiently, significantly minimising time spent and distance covered, saving on fuel. Heavy-duty automobiles can avoid routes with steep hills. You can also re-plan a hilly route for a light and medium-duty automobile.
But as you do that, ensure the route you choose doesn’t take your drivers too far. Side-step all congested routes and those that require excessive stopping and starting or cause unnecessary idling.
Drive More Efficiently
One of the proven ways to save on fuel is to manage driver behavior. Whether you’re a driver or fleet manager, you need to keep yourself or drivers accountable for how they utilize their fuel cards.
You should also reinforce ways to conserve fuel through safety training – many of the behaviors that are taught as techniques of safe driving, such as driving more efficiently. Most businesses and individuals use telematics to control driver behavior, such as harsh accelerating or braking, to maximize return on investment by minimizing fuel spend.
Keep Your Vehicle in Good Condition
If you keep your automobile in excellent condition by servicing it in line with the guidelines of the manufacturer, it’ll help you save on fuel costs. Fix any faults quickly to make sure your vehicle is operating efficiently.
When you keep your car in excellent condition, you’ll enjoy numerous benefits, saving fuel being one of them. A vehicle that isn’t serviced based on the guidelines of the manufacturer can increase the consumption of fuel by approximately 50%.
Integrate these four ways into your automobile’s daily activities, and you’ll be able to save on fuel.
