One-Way Analysis of Variance Flashcards
It involves one independent variable which has a number of different levels.
One-way Analysis of Variance
It represents the variance between the groups divided by the variance within the groups.
F-ratio
The alternative to conducting post-hoc tests after obtaining a significant omnibus F test.
Planned Comparisons
2 types of One-way ANOVA
- Between-groups ANOVA
- Repeated-measures ANOVA
It is used when there is only one independent variable with three or more levels and one dependent continuous variable.
One-way between groups ANOVA
It tests whether the variance in scores is the same for each of the three groups.
Levene’s test for homogeneity of variances
The table that you need to consult when an assumption is being violated.
Robust Tests of Equality of Means
The table that provided the statistical significance of the differences between each pair of groups and gives the results of the post-hoc tests.
Multiple Comparisons
The table that provides the means for each groups.
Descriptives
The table where you can find the values between groups that are significantly different with an asterisks.
Mean Difference
This plot provides an easy way to compare the mean scores for the different groups.
Means Plots
One of the most common effect size statistics that is provided in the ANOVA table.
Eta Squared
The section in SPSS where the information on the coefficients for each of the groups.
Contrast Coefficients
The assumption that requires that the variance of the population difference scores for any two conditions are the same as the variance of the population difference scores for any other two conditions.
Sphericity
The box in SPSS where the assumption of sphericity is being assessed.
Mauchly’s Test of Sphericity
