“Homogeneity tests,” “Estimates of effect size,” and “Observed power”. In the “Options” window, select the normal options: “Descriptive statistics,” PowerPoint slides, the researcher is generally not that interested in the results of theįirst, run the analysis as a two-way fixed factor design. The “teacher” variable is: F (4, 40) = 9, p <. As a result, you would have to conduct the analysis bothĪs a mixed effects design and a two-way fixed effects design to get theĪppropriate F test for the “teacher” variable. “teacher” variable should use the normal error value (1) as the error term, no Variable also uses the interaction effect as the error term. However, also notice that the F test for the “teacher” Also, notice that our differenceīetween treatments is not statistically significant (if you had conducted this analysisĪs a two-way fixed effects ANOVA, you would have found a statistically “treatment*teacher” interaction, which is correct. “treatment” variable is the same as the Mean Square for the “Hypothesis” for the Design: Intercept + treatment + teacher +Īs you can see in the above ANOVA table, the Mean Square “Error” term for the Variance of the dependent variable is equalĪ. You may also want “Estimates of effect size” and In the “Options” window, select “Descriptive statistics” and “Homogeneity.Options, such as descriptive statistics, so select “Options”. Before selecting “OK” to run the analysis, you will typically want some.When the “Univariate” window pops up, you want to select “y” as theĭependent variable, “treatment” as the fixed factor and “teacher” as the.2) Then, scroll down to “General linear model” and select “Univariate”. To run a mixed-effects factorial ANOVA, follow the steps below: 1) Select “Analyze” from the list of menu options at the top of the screen. The first method leads to an error for the test of the random factor, so you have to keep that in mind if you choose to run the analysis this way. There are two ways in which you can run a mixed-effects ANOVA.

We will be running an F test to determine if the treatment was effective across a random sampling of teachers.

The variable “y” is the dependent variable, which is some test of achievement. The variable “treatment” is a fixed factor since we are interested in comparing this specific treatment to the control condition. The variable “teacher” is a random factor since we are assuming that we randomly selected from the population of all possible teachers. In this file, we are comparing 5 different teachers on a treatment vs. The file we will be using is titled “mixed ANOVA design” which includes school related data. Mixed Factorial ANOVA: SPSS Procedures and Results This file will cover how to run a mixed factorial Analysis of Variance (ANOVA) design using SPSS.
