Excel Data Analysis Tool For Mac Discriptive

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

The Descriptive Statistics feature of data analysis tools is part of the 'Analysis ToolPak' add-in provided with Windows Excel, and it is not available for Excel 2011 for Mac. Instead, Microsoft recommends a third-party alternative. Your objective when using this tool is to calculate descriptive statistics for the data collected for a variable in order to understand that data better. One example might be analyzing the number of seconds it took for a race participant to run one mile. Excel isn’t meant for data analysis. But that doesn’t mean you can’t do it. Unfortunately, Excel’s statistical functions aren’t always intuitive. And they usually give you esoteric results. So instead of using stats functions, we’re going to use the go-to Excel statistics add-in: the Data Analysis Toolpak. In Data Analysis dialog box, highlight the Descriptive Statistics entry in the Analysis Tools list and then click OK. Excel displays the Descriptive Statistics dialog box. In the Input section of the Descriptive Statistics dialog box, identify the data that you want to describe. Excel like many of Microsoft’s other Office applications are extremely powerful tools that have many ‘hidden’ features. I stumbled on the Analysis ToolPak when I took an quantitative analysis class for my Masters program.

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.
