Calculating standard deviations

There is a lot of seasonal variability in the train data. To better understand this, you will now calculate the standard deviation to understand how "spread out" the data is from the mean average.

To calculate the standard deviation:

  1. Calculate the variance of the data.
  2. Take the SQRT(), or square root, of the variance.

Building on the variance, you will first manually calculate the standard deviation before defaulting to the formula STDEVP().

Übungsanweisungen

  • In cell D2, calculate the variance of the data using VARP().
  • In cell E2, calculate the square root of the variance.
  • Finally, in cell F2, use STDEVP() to automatically calculate the standard deviation.
