sample population is 50, the mean hand length is 7.0806, hand width is 7.8895, and the mean height is 67.296. 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 value of 0.424 which is less spread out, Hand width has 1.23 which is fairly spread and Height indicates the largest variance showing that it is the most spread out data. Draw a side-by-side...
