What is the mean of the z-scores?Question 2Answera.0.5b.0c.1
Solution
The mean of the z-scores in any distribution is always 0.
This is because z-scores are a measure of how many standard deviations an element is from the mean. Therefore, when you average all the z-scores in a distribution, the positive and negative values will sum up to zero.
So, the correct answer is (b) 0.
