Question

Quizplus · Accepted Answer

Measures of variability, such as range, variance, and standard deviation, indicate how scores differ from each other. They provide information about the spread or dispersion of the data points in a distribution. Pictorial formats (like graphs or charts) may help visualize the variability, but they do not provide specific numerical information. Measures of central tendency, such as the mean or median, describe a "typical" score in a distribution, but they do not provide information about variability. Additionally, measures of variability can be used to generalize from small samples, but this is not their primary purpose.
