When conducting an ANOVA, what is the purpose of an APA table? Group of answer choices   To see exactly how big of an effect the treatment had To see whether there is a pattern to the variability in the sample means To see whether you reject H0 and conclude the factor had an overall effect To see which pairs of sample means are significantly different

What does less replicates mean in the context of understanding variance of data?

If you have a study design that requires two different samples, what sort of test might you consider?    Matched samples test    Independent samples test

Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
