# How are independent samples t-tests and One-way ANOVAs similar

1. How are independent samples t-tests and One-way ANOVAs similar? How do the two tests differ? (Points : 12) Question 2. 2. What is the F-ratio? That is, what makes up the top and bottom portions of the F-ratio? (Points : 10) Question 3. 3. A social psychologist conducted a study examining the effectiveness of two persuasion techniques. She found the following information in her ANOVA table: SS between = 45. 55SS within = 30. 22SS total = 75. 77Using eta squared, calculate the effect size for her study? What does this mean?
