Stdev Vs Variance. Which describes how the samples or the observations are spread out around the average or the mean. Variance vs standard deviation are the 2 types of an absolute measure of variability.
On the other hand the standard deviation is the root mean square deviation. Moreover it is hard to compare because the unit of measurement is squared. So now you ask what is the variance variance.
Standard deviation and variance.
Which describes how the samples or the observations are spread out around the average or the mean. Its symbol is σ the greek letter sigma the formula is easy. The easy fix is to calculate its square root and obtain a statistic known as standard deviation. Moreover it is hard to compare because the unit of measurement is squared.
