b. Briey explain the difference between the range and the interquartile range as a measure of dispersion. The (1) is computed using only the middle 50% of the values in the data set. The (2) is computed using all of the values in the data set. The (3) is very sensitive to extreme values and, thus, is considered a weak measure of variation, whereas the (4) is not sensitive to extreme values. (1) O interquartile range (2) O interquartile range (3) 0 range 0 range O range 0 interquartile range (4) O interquartile range 0 range
