variance equations. Created by Sal Khan. The variance of a random variable tells us something about the spread of the possible values of the variable.

In probability theory and statistics covariance is a measure of the joint variability of two random variables. So lets try that over here. Formula to Calculate Population Variance Population variance formula is a measure by the average distances of population data and it is calculated by finding out the mean of population formula and variance is calculated by Sum of the square of variables minus mean which is divided by a number of observations in population.
If the greater values of one variable mainly correspond with the greater values of the other variable and the same holds for the lesser values that is the variables tend to show similar behavior the covariance is positive.
In the opposite case when the greater values of one. Variance Formula In probability theory and statistics the variance formula measures how far a set of numbers are spread out. The variance of a random variable tells us something about the spread of the possible values of the variable. Instead you add the variancesThose are built up from the squared differences between every individual value from the mean the squaring is done to get positive values only and for other reasons that I wont delve into.
