Two-way ANOVA is used when
Select one:
a. Analysing the differences between two independent variables
b. Analysing the results of a two-tailed test
Oc Analysing the difference between two population means
O d. Analysing the results from a large sample
What test would be best to use if there was a statistical difference between brands in an experiment? Would it be a one way ANOVA since that is used to see if there are any differences within a group?
Why would a researcher choose to conduct an One-Way ANOVA rather than multiple independent samples t-tests?
