Relevance and Uses of Variance Formula From a statistician’s perspective, Variance is an essential concept to understand. It is often used in probability distribution tomeasure the variability (volatility)of the data set vis-à-vis its mean. The volatility serves as a measure of risk, and as ...
Until now, we have discussed how to calculate the variance of a random variable. However, there is another concept, that of sample variance, that applies when we need to assess the dispersion of some observations around their sample mean. If you are interested in the formulae for sample vari...
The variance formula is used to calculate the difference between a forecast and the actual result. The variance can be expressed as a percentage or an integer (dollar value or the number of units). Variance analysis and the variance formula play an important role in corporatefinancial planning a...
