EXAMPLE 2.9.4

To paraphrase Benjamin Disraeli: "There are lies, darn lies, and DAM STATISTICS."

Compute the mean, median and mode for the following DAM STATISTICS:

SOLUTION

Mode

The mode is 440 ft., since 440 occurs more frequently than any other value.

Mean

In this distribution n = 7, so the mean is the sum of all seven data points, divided by 7.

Median

The seven data points are already arranged in numerical order, so the median will be the fourth data point.

Median = 568 feet
