WebMar 2, 2024 · Statistics from the sample are used to describe the population. Shape, center, and spread of data are statistical measures and concepts that are useful in understanding and explaining data. Common measures of location, or central tendency, are the arithmetic mean, median, mode, and interquartile mean. Common measures of statistical dispersion are the standard deviation, variance, range, interquartile range, absolute deviation, mean absolute difference and the distance standard deviation. Measures that assess spread in comparison to the typical size of data values include the coefficient of vari…
