Standard Deviation is the square root of Variance (either Population Variance or Sample Variance). You can verify the result by multiplying VAR.P(A1:A10) by N and multiplying VAR.S(A1:A10) by n-1, the results are equal. The syntax of both formula only contain one argument, which is the Range of value. You may use VAR.P to calculate Population Variance while VAR.S to calculate Sample Variance. Sample Variance (used when the population is unknown, using sample data to estimate the population)Д«oth of the above formula are basically the same except that Population Variance divides the result by N while Sample Variance divides the result by n-1. Population Variance (used when the population is known) Larger Variance means the data are more spread out. There are two kinds of Variance вЂ“ Sample Variance and Population Variance. Variance is defined as the average of the squared differences from the Mean. Suppose data set 1, 3, 5, 7 lie in Range A1:A4. To calculate Interquartile Range in Excel, use either PERCENTILE.EXC or PERCENTILE.INC Function to separately calculate P25 and P 75, and then find the difference.

To understand how to calculate percentile, click here to read my previous post. Interquartile RangeДЄnother type of Range called Interquartile Range (IQR) which measures the difference between 75th and 25th observation using the below formula.

Range only reflects the difference between largest and smallest observation, but it fails to reflect how data is centralized. Range = largest observation - smallest observation Range is the easiest way to describe dispersion using the below formula. Variability is also known as dispersion, it is to measure of how data are spread out.ДЇor example, data set 100, 130, 160 is less spread out than data set 1, 50, 100, 150, 200 In this tutorial, I will explain how to measure variability using Range, Variance, Standard Deviation. In the previous post, I have explained how to measure the central tendency using Mean, Mode, Median. This Excel tutorial explains how to measure variability using Range, Variance, Standard Deviation.Д®xcel calculate Covariance, Coefficient of Correlation Excel Range, Variance, Standard Deviation
