The symbol is σ. This composite cell range consists of all the values from A2 through A11. Which function in Excel do we use to calculate the standard deviation of a sampled data set? A larger standard deviation value means the data is spread further away from the mean. This deviation (also called variance) is nothing but the average of the squared differences from the mean. Although STDEV is specified as taking a maximum of 30 arguments, Google Sheets supports an arbitrary number of arguments for this function. If we need to do it for a population instead, we can use the STDEVP formula. It is interesting to learn that the variance is nothing but the square of the standard deviation, another important metric in statistics. If you need to find the standard deviation for a population instead, you will need to use the STDEVP formula. With the cursor still on the same cell, now click in the formula bar at the top of the spreadsheet (the white box next to the “=” sign) to put the cursor in that bar so you can edit the formula. What Excel version are we using? Click on the X axis using the right navigation bar and select the cells which you want to use for the X axis. Otherwise, you will get a #DIV/0!
