Question
Based on sample quiz score data, an instructor found that the average distance from the mean quiz score was 1.25. This measurement reflects the1 pointrange.deviation score.standard deviation.variance.
Solution
This measurement reflects the standard deviation. The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. In this case, the average distance from the mean quiz score is 1.25, which is the standard deviation.

Question 10Drs. Melnyk and Ahmed conducted a study in which 400 participants completed a 50-point test about their knowledge of statistics. The mean score was 40 with a standard deviation of 5. These results approximated a normal distribution, which means that the probability of a score between 0 and 1 standard deviations was about 34.1%, between 1 and 2 standard deviations was about 13.6%, and above 2 standard deviations was about 2.3%.
