• We may have a specific result to look for with regard to our interaction • For example, we may think based on past research moderate arousal should result in optimal performance for difficult items • We would assign contrast weights to reflect this hypothesis: Is moderate different fro...

A factorial analysis using ANOVA has the advantage that it will always produce a good fit to the cell means. A regression analysis may be able to produce a reasonably good fit using fewer degrees of freedom for the model, and perhaps lead to greater understanding of the effects. Example 9.5...

If the hypothesis of equal cell means is rejected, the next step is to determine whether these differences are due to specific main or interaction effects.1 9.3.5 The Factorial Analysis The linear model for the factorial experiment defines the cell means in terms of the elements of the ...
Interaction hypothesis definition: A hypothesis predicting that one independent variable changes the other independent variable’s impact on the dependent variable Interaction: The impact of the self-esteem on the ability to accurately detect nonverbal communication will be enhanced for those who experience...
Since the p-value of 0.0015 for the menu items is less than the .05 significance level, we reject the null hypothesis that the mean sales volume of the new menu items are all equal. Moreover, the p-value of 1.2e-05 for the east-west coasts comparison is also less than the .05 sig...
Hypothesis Testing: Factorial ANOVA Hello! So I had to propose a research design as an assignment and I chose to look at cognitive function in an exercise group vs. a control group over the period of 10 years. -subjects are tested at the beginning and end of each year The groups were...
What do the overlapping bars in this plot suggest for a factorial ANOVA? Factorial Design: The factorial design is a variation of the quantitative design that can be used to investigate whether or not the effect of an independent variable (IV1) on a dependent variable (DV) is in...
If ART = FALSE, then an ANOVA is used. Like the sic function, mic.test takes response times from each of the salience conditions as input. It then returns the exact p-value and test statistic from the chosen test. Example 1 demonstrates the use of the sic function applied to data ...
