Excel provides a number of data analysis tools, which are accessible via **Data > Analysis|Data Analysis**.

If this option is not visible you may need to first install Excel’s analysis tool pack. This is done by selecting **Office Button > Excel Options > Add-Ins **in Excel 2007 or **File > Help|Options > Add-Ins **in Excel 2010/2013, and clicking the **Go** button at the bottom of the window. Next you select the **Analysis ToolPak** option on the dialog box that appears and click the **OK **button. You will then be able to access the data analysis tools.

After selecting** Data > Analysis|Data Analysis** you will be presented with the dialog box in Figure 1.

You can now select any one of the following options useful for statistical analysis:

- ANOVA: Single Factor
- ANOVA: Two-Factor with Repetition
- ANOVA: Two-Factor without Repetition
- Correlation
- Covariance
- Descriptive Statistics
- Exponential Smoothing
- F-Test: Two Sample for Variances
- Histogram
- Random Number Generation
- Rank and Percentile
- Regression
- Sampling
- t-Test: Paired Two Sample for Means
- t-Test: Two-Sample Assuming Equal Variance
- t-Test: Two-Sample Assuming Unequal Variance
- z-Test: Two-Sample for Means

Each of these options represents a data analysis tool that will be described in this website. Now suppose by way of example that you choose **Anova: Single Factor**. You will now be presented with the dialog box shown in Figure 2.

The **Input Range** consists of the Excel range where the data elements to be analyzed are stored. Suppose, by way of example, this data consists of a 4 × 8 array representing 4 treatments as in Figure 3.

In this case you insert the range B2:E9 in the **Input Range** field (of the dialog box of Figure 2) and select the **Columns** radio button. If you had assigned a name (e.g. Study1) to the range B2:E9 then you could put this name in the Input Range field instead of B2:E9.

Alternatively you could insert B1:E9 in the **Input Range** field and check the **Labels in First Row** checkbox in the dialog box to indicate that you have included the column headings in the data range. Note that the participant numbers (in column A) are not used.

If the data were arranged where the treatments are listed by row instead of column, then you would select the **Rows** radio button and you could optionally select the **Labels in First Column** checkbox.

The **Alpha** value (as described in Null and Alternative Testing) is set to 0.05 by default, although you can optionally change this to 0.01 or some other value.

You can now choose the **New Worksheet Ply** radio button from the **Output** options (and leave the data field blank). In this case a new worksheet is created (in the tab prior to the current one) and the ANOVA report is placed in this worksheet starting at cell A1. You can then copy the results to the current worksheet (or anywhere else you like).

Alternatively, you can choose the **Output Range** or **New Workbook** radio button, to put the report in some specific output range that you choose or in a new workbook.

You might want to add, that for Mac Excel 2013, the data analysis menu appears in the top menu bar as a drop down menu, called “Real Statistics”.

Tina,

This is a good point, but I wasn’t aware of an Excel 2013 version for the Mac. I believe the latest release of Excel for the Mac is Excel 2011. In the bundling of Excel 365 for the Mac, perhaps Microsoft is relabeling Excel 2011 as Excel 2013. Do you know whether Excel 2013 for Mac is different than Excel 2011?

Dear Dr. Charles

Being a novice in statistics, I came across ANOVA first time on this web page. Could you please explain the fundamentals of ANOVA, what is it, what is its significance, etc.? That would really be helpful for me as well as others who are new into this field.

Thanks

I suggest that you look at the following webpage which will direct you to lots of information about ANOVA.

Dear Zaiontz,

Truly grateful to you for the wonderful Resource Pack. I encountered a problem here. I installed the resource pack by following your instruction for installation. Installation was smooth and successful, and I tested out several functions of the program and found everything was fine. However, the next day when I came back to use it, I did not even see the program name inside AddIn. Could you please tell me how to correct the problem? Thanks a lot.

Do the functions and data analysis tools still work?

Charles
