Question

Quizplus · Accepted Answer

Variance and standard deviation are the most widely used measures of dispersion because they are based on all the data points and provide a measure of the average deviation from the mean. Range and interquartile range are less commonly used because they only consider the extremes or the middle 50% of the data, respectively. Covariance and correlation coefficient are used to measure the relationship between two variables, rather than the variability within a single variable.
