Are you currently solving an assignment on standard deviation and variance? Then you are going to need a variance calculator, especially if you are working with descriptive statistics, hypothesis testing, statistical interference, etc. These calculators help you out when you have to solve a lengthy numerical or dry-run code. This is because the sample variance formula finds application in many fields like Computer Science, Economics, etc.
Read on to get further insight into variance and our calculator.
If you are wondering what is variance in statistics, then this section is for you. A statistical measurement of the dispersion between values in a data collection is known as a variance. Variance expresses how far each number in the set deviates from the mean, and thus from every other number in the set. The symbol that is frequently used to represent variation is σ2.
Data points with low variance are often similar and do not deviate much from the mean. The term "high variance" refers to data values that are more variable and separated from the mean.
However, if you are unable to understand what is the variance in a particular numerical, you should use the free variance calculator. You can use it any number of times you want without paying a subscription fee.
Now, you must be wondering what is the sample variance formula. Well, you are about to find out in this section.
σ2=
Here n is the sample size, and the x-bar represents the sample mean. When you use our sample variance calculator, you just have to type these values.
Now, you need to know the population variance formula, if you wish to know how to find the population variance.
Here, N refers to the size of the population, and the μ stands for the population mean.
Similar to the previous one, when you use our population variance calculator, you have to put in the value of N and μ.
