Measures of variation provide information about the________.

Question

Quizplus · Accepted Answer

Measures of variation, such as range, variance, and standard deviation, provide information about the spread or dispersion within a distribution of scores. They help to identify how similar or different the scores are from each other, and provide a more complete picture of the data than just the measure of central tendency (such as the mean). Therefore, option B, which mentions the variety within the distribution of scores, is the correct answer. Option A is incorrect because measures of variation do not directly provide information about the typical or most common score (that would be a measure of central tendency). Options C and D are also incorrect because measures of variation are not related to the size of the sample or the adequacy of the selection criteria.
