Why would it NOT make sense to calculate z scores for the following sample of scores: 3, 5, 31, 42, 38, 39, 40, 29, 33?
What will be an ideal response?
Ans: This is not a normal distribution. With the two particularly low scores of 3 and 5, we have a negatively skewed distribution and cannot calculate meaningful z scores. The use of z scores requires a normal distribution of data.
