## Calculating the Mean and Standard Deviation with Excel

I’m going to explain to you How To Calculate Standard Deviation In Excel With Very Steps.

#### 1. Finding the Mean:

First of all Enter the scores in one of the columns on the Excel spreadsheet (check the example below). After entering the data, place the cursor where you want to display the Average, and then click the mouse button.Select Insert Function (fx) from the FORMULAS tab. Then A dialog box will appear. Select AVERAGE from the Statistical category and click OK. (Note: If you want the Median, select MEDIAN. If you want the Mode, select MODE.SNGL.Excel only provides one mode. If a data set had more than one mode, Excel would only display one of them.) Enter the cell range for your list of numbers in the Number 1 box.For example, if your data were in column A from row 1 to 13, you have to enter A1:A13. Instead of entering the range, you can move the cursor to the beginning of the set of points you want to use. After entering the list range, click OK at the bottom of the dialog box. The Mean (average) for the list will appear in the cell you selected.

#### 2. Finding the Standard Deviation

Place the cursor where you want to display the standard deviation and click. Select Insert Function (fx) from the FORMULAS tab.A dialog box will appear. Select STDEV.S (for a sample) from the Statistical category. (Note: If your data are from a population, click on STDEV.P).

After you have made your selections, click on OK at the bottom of the dialog box. Enter the cell range for your list of numbers in the Number 1 box. For example, if your data were in column A from row 1 to 13, you would enter A1:A13. In addition to the input range, you can also move the cursor to the beginning of the set of points you want to use, and then click and drag the cursor over it. After entering the list range, click “OK” at the bottom of the window Dialog box. The Standard deviation for the list will appear in the cell you selected.
