Question
For one test's distribution (mean=500, Standard deviation=108) and another tests distribution (mean= 24, standard deviation= 4) which score is relatively higher, a score of 674 on the first test or a score of 21 on the second test? Explain.
A. The first score is relatively higher than the the second score because the z-score of the score on the first test is greater than the z-score on the second test.
B.the test score is equally high because the z score of the score on the first is equal to the z score of the score on the second test
C.The second score is Relatively higher than the first score because the z score of the score on the first test is less than the z score of the score on the second test
D. The first score is relatively higher than the second score because the z score of the score on the first test is equal to the z score of the score on the second test
Explanation / Answer
Z score = (Score - mean)/standard deviation
Z score for first test = (674 - 500)/108 = 1.61
Z score for second test = (21 - 24)/4 = -0.75
A. The first score is relatively higher than the the second score because the z-score of the score on the first test is greater than the z-score on the second test
