7-113.
Alan collects rocks. He weighs them before he puts them in piles in his backyard. In the last two weeks, he has recorded the following weights:
Make a stem-and-leaf plot to help him organize the information so that he can get a better idea of how hard he is working.
Refer to problem 6-18 for an example of a stem-and-leaf plot.
Find the mean, median, and mode for the information.
Don't remember what mean, median, and mode are?
Go back to problem 1-110 and look at the work done for that problem.Which measure of central tendency was most affected by the outliers of
pounds? Remember that an outlier is a piece of data which does not fit with the rest of the data.
The mean was most affected. Can you explain why?
