On 15c, Step 3, the key says that SMD = 1. Describe the calculations you did to get that number. Note: SMD is not written quite right on this question, because Canvas will not allow me to do a subscript on a subscript. If it were perfectly correct, the "M" would be a subscript on the "S," and then the "D" would be a subscript on the "M." Group of answer choices SS of the difference scores = 100, and from there we get variance of 16 and standard deviation of 4. To get SMD, we divide standard deviation of 4 by square root of n=16. SS of the difference scores = 80, and from there we get variance of 12 and standard deviation of 3.46. To get SMD, we divide standard deviation of 3.46 by square root of n=12. SS of the difference scores = 30, and from there we get variance of 6 and standard deviation of 2.45. To get SMD, we divide standard deviation of 2.45 by square root of n=6
