Stats Chapter 14: two way ANOVA
each of the following is type of two-way ANOVA except
a 1 between factorial design
a researcher has participants complete a survey regarding their level of restraint when eating. participants were assigned to groups based on their current health status (lean, overweight, obsessive) and gender (male, female). what type of factorial design is most appropriate for this study?
a between subjects factorial design
a simple main effect test is appropriate for analyzing which significant result?
a significant interaction
an estimate of effect size with the two-way ANOVA is typically reported for
a significant main effect test and a significant interaction tests
the complexity of the two way ANOVA differs from that of the t tests and the one way ANOVA in that
an interaction can be observed using the two way ANOVA but not using the t-tests and the one way ANOVAS three hypotheses are made with one statistic test using the two way ANOVA but not using the t tests and the one-way ANOVAs two factors can be observed using the two way ANOVA, but not using the t-tests and the one-way ANOVAs
the denominator of the test statistic for the main effects and interaction in a two way between- subjects ANOVA
is equal to mean square error
what hypothesis identifies a prediction that requires that two factors we observed in the same statistical design?
mood will improve most when people consume foods that are high in sugar and fat
a researcher conducts a 2 x 4 between subjects ANOVA in which 12 participants were observed in each group. if SSa= 18 and SSe= 264, then what is the decision for Factor A at 0.05 level of significance using the two way between subjects ANOVA?
reject the null hypothesis
for an analysis of variance, the term "two-way" refers to
the number of factors in the design
a researcher computes a 3 x 4 between subjects ANOVA and finds one significant main effect and a significant interaction. what is the next appropriate step?
compute simple main effect tests for the interaction
for a two way ANOVA, the ____ should also be reported for each significant hypothesis test and for the simple main effects tests
effect size
a researcher measures differences in recall between participants watching a regular or a 3-D movie clip with a romance, drama, or action theme. Different participants were observed in each group. what type of statistical design is appropriate for this study?
two way between subjects ANOVA
