Terms_Measures of Varation

Question 1

extent of variation between empirical and theoretical score

Answer 1

deviation from the mean (also error, discrepancy)

Question 2

shows amount of variation between scores

Answer 2

squared deviation from the mean (also squared errors)

Question 3

2D representation, or area of variation between scores

Answer 3

squared deviation from the mean (also squared errors)

Question 4

total amount of variation in the sample

Answer 4

squared deviation from the mean (also squared errors)

Question 5

estimates totality of how varied the observed score is from the mean

Answer 5

sum of squares

Question 6

average squared deviation from the mean

Answer 6

variance

Question 7

Answer 7

variance

Question 8

typical or average extent of variation in the sample

Answer 8

standard deviation

Question 9

average deviation from the mean

Answer 9

standard deviation

Question 10

raw score minus mean over the standard deviation

Answer 10

standardized score (z-score)
