# How to Do Descriptive Statistics in MS Excel 2007

"Statistical Techniques in Business and Economics" describes descriptive statistics as methods used to organize, summarize and present data in an informative way. These statistics can be computed and generated using Excel 2007 as long as you have installed the Data Analysis ToolPak or add-in. The software generates statistical conclusions, such as the mean, median, mode, standard deviation, standard error, kurtosis, sample variance, skewness, range, minimum, maximum, sum and data count. The results can help you make more informed decisions.

Install the Microsoft Office Analysis ToolPak. Click the "Microsoft Office Button" and then "Excel Options."

Click "Add-ins" and then "Excel Add-ins" located in the Manage box. Click "Go."

Open Excel to generate a new spreadsheet.

#### Step 3

Type the label of your first column in cell 1A. Enter the data values that you are evaluating in the cells directly below your label.

Click on the small chart box located to the right of the input range. Highlight the spreadsheet column containing the data that you want to summarize. Do this by holding down the left mouse button and highlighting all of the data in the column you want to select. This data will be placed in your input range. Click on the small chart box again to return to the Descriptive Statistics box. If you also highlight the label, click on "Labels in First Row" on this screen.

#### Step 8

Click "Output Range" and indicate to which cell you want the results to go. For example, choose cell H1 by typing "H1" in the output range.

#### Step 9

Select "Summary Statistics" and click "OK." The descriptive statistics are now generated. Double-check the count in the results to make sure it included the correct number of items from your list of data.
