What Is VarianceThe Variance is defined as: The average of the squared differences from the Mean. To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference ). Then work out the average of those squared differences. ( Why Square?). In probability theory and statistics variance is the expected value of the squared deviation from the mean of a random variable The standard deviation is obtained as the square root of the variance Variance is a measure of dispersion meaning it is a measure of
