If we have a small set of values, it’s possible to calculate the variance by hand in only five steps. For large data sets, we saw how simple it is to calculate variance using Python and Pandas.

If you’re wondering how to find the variance in your data set, look no further. Here’s how to calculate variance in a snap with Pandas.

The variance-covariance method for the value at risk calculates the standard deviation of price movements of an investment or security.

There are three methods of calculating Value at Risk (VaR), including the historical method, the variance-covariance method, and the Monte Carlo simulation.
