- Click on the Office Button at the top left of the page and go to Excel Options .
- Click on Add-Ins on the left side of the page.

Excel for Mac 2011 and higher do not include the analysis tool pack. You can't do it without a different piece of software. This was by design since Microsoft does not like Apple.

Enter the data into the spreadsheet that you are evaluating. You should have at least two columns of numbers that will be representing your Input Y Range and your Input X Range. Input Y represents the dependent variable while Input X is your independent variable.
-
Open the Regression Analysis tool.
- If your version of Excel displays the ribbon , go to Data , find the Analysis section, hit Data Analysis , and choose Regression from the list of tools.
- If your version of Excel displays the traditional toolbar , go to Tools > Data Analysis and choose Regression from the list of tools.
-
Define your Input Y Range. In the Regression Analysis box, click inside the Input Y Range box. Then, click and drag your cursor in the Input Y Range field to select all the numbers you want to analyze. You will see a formula that has been entered into the Input Y Range spot.
-
Repeat the previous step for the Input X Range.
-
Modify your settings if desired. Choose whether or not to display labels, residuals, residual plots, etc. by checking the desired boxes.
-
Designate where the output will appear. You can either select a particular output range or send the data to a new workbook or worksheet.

QuestionHow do I calculate standard error?Community AnswerStep 1: Calculate the mean (Total of all samples divided by the number of samples). Step 2: Calculate each measurement's deviation from the mean (Mean minus the individual measurement). Step 3: Square each deviation from mean. Squared negatives become positive.

QuestionHow can I calculate the equation of a line in regression in Excel?Community AnswerOne quick way to do this is to arrange your X and Y variables in adjacent columns (X on the left), then select the two-column range and use the Insert/Scatterchart command to insert an X-Y scatterchart. Then right-click on the chart, choose Add Trendline from the drop-down menu, and then check the box for Display-Equation-on-Chart. Or, you could use some good software to fit the whole regression model. Try RegressIt, a free add-in (available at regressit-dot-com), It gives very detailed and well-designed output, and among other things it will show the equation for any number of independent variables. Just click the "Show All" button after fitting a model.
