The determination of statistical significance of a mean makes use of:
A) the correspondence between z-scores and areas under the normal curve
B) the relationship between raw scores and percentile values
C) the calculation of the range of scores
D) the relationship between a frequency distribution and a frequency polygon

Question

Quizplus · Accepted Answer

The determination of statistical significance of a mean often involves calculating a z-score, which represents the distance of a data point from the mean in terms of standard deviations. This z-score is then related to areas under the normal curve to determine the probability of observing such a mean if the null hypothesis were true, thus assessing statistical significance.
