Quizplus · Accepted Answer

The coefficient of variation is defined as the ratio of the standard deviation to the mean, expressed as a percentage. Therefore, option B, which states that the coefficient of variation is the standard deviation divided by the mean times 100, is the correct answer. Option A, stating that the coefficient of variation is the same as the variance, is incorrect. Option C, stating that the coefficient of variation is the square of the standard deviation, is also incorrect. Option D, stating that the coefficient of variation is the mean divided by the standard deviation, is the reciprocal of the correct answer, and is incorrect.
