How To Calculate Standard Deviation In Excel Quick Guide

For example, if you select column “A” as the area in which to enter your data, you might type a number into cell A1, cell A2, cell A3, and so on. If needed, you can move columns in your spreadsheet to organize your data.

The selected function will either calculate the standard deviation for a sample (using n - 1) or a population (using n), where n is the sample size. The selected function will include or exclude logical values (TRUE and FALSE) and text (numbers represented as text). TRUE is interpreted as a 1, while FALSE is 0.

STDEV. P — Finds the standard deviation of a population. This function doesn’t include logical values or text.

=STDEV. S()

In between the parentheses, type the letter and number of the cell containing your first data value. Type a colon (:) Type the letter and number of the last cell. For example, if you entered your data in column “A” from rows 1 through 10, you would have =STDEV. S(A1:A10) typed here. If you just want to display the standard deviation of the value of a few scattered cells such as A1, B3, and C5, you can type the cell names separated by commas (e. g. , =STDEV. S(A1,B3,C5)).

If you want to check your work, you can calculate the standard deviation by hand.
