The Empirical Rule says that for a normal curve, approximately 68 of the values fall within 1 standard deviation of the mean in either direction, while 95 of the values fall within 2 standard deviations of the mean in either direction. Explain why you don't have twice as many values within 2 standard deviations as you do within 1 standard deviation.

Question 2

A(n) __________ represents the number of standard deviations the observed value or score falls above or below the mean.
 Fill in the blank(s) with correct word
