Multiple Choice

15,467 people rated how much they liked my textbook on a scale of 1 (it is rubbish) to 10 (I love it) . The distribution of scores had a skew of 1.23 (SE = 0.65) . Which of the following would be the best way to decide whether the skew is problematic? (Hint: Think about what you know about the central limit theorem.)

A) Use the Kolmogorov-Smirnov test.
B) None of the options, because of the large sample size.
C) See if the z-score is bigger than 1.96 or smaller than -1.96
D) See if the skew is significant at p < .05.
