Question

The median rainfall during a spring storm in the lowlands is about 4 mm less than a spring storm in the highlands. The mean rainfall for the lowlands is about 3 mm less than for the highlands. Why is there a difference in the central measures for each data set?

Answer 1

The mean and the median are different  because the data for the highlands has more variation than the data for the lowlands. The mean is affected by the outliers in the lowlands data.

Answer 2

Median is just the value that is neither the highest nor the lowest compared with the other values in the set

Mean is just the average of the numbers which is found out by adding up all the numbers then dividing the sum by the number of values in the set
