Sample Statistics

The range is another measure of how spread out the data are. Because it only uses two values, the largest and the smallest, the range is easy to calculate. It is also very unstable as an estimator of the population range. To illustrate calculating the range, assume that you collected the following 6 data values:

18, 16, 85, 36, 69, 2

Calculate the range of this sample.

In the box below, please enter the sample range of the data given above, then click on the “Check your answer!” button. Please round your answer to the ten-thousandths place.
