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

mean means average, sum over number of sprinkles/ number.
Median means half the sprinkles were higher and half lower.
If most sprinkles were sprinkles and one was a hurricane, the median would be about in the middle but the average would be pulled way up by the big rainstorm.

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.
