When the dialog box in Figure 1 appears, enter A3:C27 in the Input Range, click on Column/row headings included with data, select Standard format as the Input Format, select ANOVA as the Analysis Type and click on the OK button. To do this, click on cell E1 (where the output will start), enter Ctrl-m and select the Two Factor ANOVA option from the menu that appears. The rows can be listed in any order.Įxample 3: Perform an analysis of variance for the data in range A3:C27 of Figure 7.įigure 7 – Two Factor ANOVA on data in standard format The first column contains the row group names ( blends in the above example), the second column contains the column group names ( crops in the above example) and the third column contains the corresponding scores ( yield in the above example). This format consists of a range with three columns. The Excel format is the one used by Excel, as described in Figure 3 The data analysis tool also supports what we will call the standard format, also called stacked format. Two input formats are supported by the data analysis tool. Upon pressing the OK button, the output is as shown in Figure 6.įigure 6 – Crops Simple Effects Stacked input format Note that you need to enter the group means range (as shown in range H12:K14 of Figure 3) in the Input Range field. After pressing the OK button, fill in the dialog box that appears as shown in Figure 5.įigure 5 – Dialog box for Two Factor ANOVA Follow-up tests This is done by pressing Ctrl-m, double-clicking on the Analysis of Variance option (or clicking on the Anova tab if using the Multipage interface) and selecting the Two Factor ANOVA Follow-up option (as shown in Figure 1). In addition to the analysis of the main effects (Blend and Crop in the above example), The Real Statistics Two Factor ANOVA Follow-up data analysis tool can be used for a variety of follow-up tests, including contrasts and Tukey’s HSD, as well as simple effects, as shown in the next example.Įxample 2: Show the analysis of the Crops simple effects for the data in Figure 3. The output is shown in Figure 4.įigure 4 – Exchanging rows and columns in input data range
To do this for the data in Example 1 check the Display input flipping rows and columns option shown in Figure 2. This will be useful when performing follow-up analyses (see for example Contrasts for Two Factor Anova). Observation: The data analysis tool also provides the option to exchange the rows and columns of the input range. Observation: If the Number of Rows per Sample field is set to 1, then two-factor ANOVA without replication is used. Note that the Interaction table (range G11:L15) is as Figure 3 of Two Factor ANOVA with Replication, and can be used to create the charts shown in Figure 4 of that webpage. Three tables of descriptive statistics, as well as the ANOVA results, are produced. The output is shown in Figure 3.įigure 3 – Two Factor ANOVA data analysis
Next, insert 5 in the Number of Rows per Sample field and click on the OK button. The dialog box shown in Figure 2 will now appear.įigure 2 – Dialog box for Two Factor AnovaĮnter A4:E19 in the Input Range, click on Column/row headings included with data, select Excel format as the Input Format and select the ANOVA as the Analysis Type. The dialog box shown in Figure 1 will appear.įigure 1 – Dialog box for Analysis of VarianceĬhoose the Anova: two factors option and click on the OK button. Real Statistics Data Analysis Tool: The Real Statistics Resource Pack provides the Two Factor ANOVA data analysis tool, which we demonstrate in the following example.Įxample 1: Perform the analysis of Example 1 of Two Factor ANOVA with Replication using the Real Statistics Two Factor ANOVA data analysis tool.Ĭlick on cell G1 (where the output will start), press Ctrl-m and double click on the Analysis of Variance option (or click on the Anova tab if using the multipage interface). Data analysis tools based on Excel input format Observation: These functions also support Two Factor ANOVA without Replication by setting the value of r to 1. Similarly, ATESTInt(B5:E9, 5) = 0.04556, which is the same as cell 元2 of Figure 3 on that webpage. Figure 2 on that webpage), MSRow(B5:E19, 5) = 4391.45, which is the same result obtained in cell J30 of Figure 3 of that webpage. Observation: For example, referring to Example 1 of Two Factor ANOVA with Replication (esp. The second argument for the column and interaction functions is optional and can be dropped. Here R1 contains the sample data and r is the number of rows for the A factor. Real Statistics Excel Functions: The Real Statistics Resource Pack supplies the following functions.
