Same response as to the other question:

The usual methods to find the average are: mean, median, and mode.

The range is not a method to find the average.

If you are specifically asked to find the mode, do so; otherwise **do not use the mode to find the average**.

Use the mean unless there is an outlier which will strongly influence the mean; if there is that kind of outlier, use the median.

For this data set is there an outlier (a number that is very, very much larger or smaller than the rest of the data)?

If there is, use the median, if not use the mean.
