Answer 1

First, you want to put them in order from least to greatest, so it should me Order: 78,88,87,92,93,94,96,100. You want to start by finding the mean, which the average of the dated divided by the number of numbers in the set. Find the absolute value of the difference between each data value and the mean: (data value – mean).Find the sum of the absolute values of the differences. Divide the sum of the absolute values of the differences by the number of data values.
