The median is the value at the middle of the observed data, and in this output, we have hand length to be 7, hand width is 8 and height 67. The difference between the maximum and the minimum data values give the Range, and in the data, we have Hand length 3.25, hand Width 6 and Height 17. The variance indicates how much the data is spread out from the mean, and from the output hand length has a...
