While these functions don't directly calculate variance, they are often used as part of the process. Variance is calculated by finding the average of the squared differences from the mean, so you would use the AVERAGE and SUM functions to calculate the mean, and the COUNT function to determin...

Expected Value:The expected value, also called themeanfor a Poisson distribution is the predicted number of times an event occurs in a certain time frame. We will use these steps, definitions, and equations to calculate the mean or expected value of a Poisson distribution in the fo...
The Sharpe ratio usesstandard deviation, which is a mathematical measure of the dispersion of values within a range. To calculate standard deviation, first find the mean by adding all values and dividing by the number of values in the dataset. Then calculate the variance for each value by subt...
