In the drug Level1 subgroup, select column d1d1 as the dose Level1 input data range. Now under the Data branch, there are three subgroups.If one factor is a non-repeated measures factor, just uncheck the Repeated check box. Notes: Factor A and Factor B are set as repeated measures factor by default (The Repeat check box under Factor is checked ). Set 3 and 2 for Number of Levels in Factor A and Factor B drop-down list to specify levels of the factor.

In this example, there are two factors.

In Input tab, select Raw from the Input Data drop-down list.

Select Statistics: ANOVA: Two-Way Repeated Measures ANOVA to open the dialog.

Drag-and-drop this file into the empty worksheet to import it. In this folder, open the Statistics\ANOVA subfolder and find the file Two-Way_RM_ANOVA_raw.dat. If there is significant difference, we will perform pairwise comparison to determine of which level the effects are different. We will perform the Two-Way Repeated Measures ANOVA to determined whether the drug type and dosage have significant effect on a subject. In this example, we are interested in whether different drugs and doses have different effects on subject. When the Raw data mode is used, the different factors and levels should be in different columns. For Two-Way repeated measures ANOVA, if the indexed mode is used, data should be organized into four columns: Factor A, Factor B, Data, and Subject. Origin can perform Two Way Repeated Measures ANOVA in both indexed and raw data modes.

Interpret results of a Two-Way Repeated Measures ANOVA.

Perform Two-Way Repeated Measures ANOVA.

Input raw data in the statistical analysis dialog.

Minimum Origin Version Required: Origin 8.6 Pro SR0 What you will learn In the following example, the two factors are the repeated measures factors. If any repeated factor is present, then the repeated measures ANOVA should be used. Two-Way Repeated Measures ANOVA designs can be two repeated measures factors, or one repeated measures factor and one non-repeated factor. Using a standard ANOVA in this case is not appropriate because it fails to model the correlation between the repeated measures, and the data violates the ANOVA assumption of independence. Similar to two-way ANOVA, two-way repeated measures ANOVA can be employed to test for significant differences between the factor level means within a factor and for interactions between factors. "Repeated-measures" means that the same subject received more than one treatment and/or more than one condition. For Two-Way Repeated Measures ANOVA, "Two-way" means that there are two factors in the experiment, for example, different treatments and different conditions.
