Below are the forearm length and the hair length of 10 9th grade math students. Find the following for each: mean, median, mode, range and standard deviation. Draw a histogram, box and whisker plot (may not be created using a website) and choose the appropriate measure of center for each.

QUESTIONS: 1. Which measurement has a higher standard deviation? Why do you think that measurement has the higher standard deviation?
2. What type of distribution does the histogram for each measurement show? Forearm length: Hair length:
3. Looking at the box and whisker plot for the hair length, are there any larger or smaller sections? Why do you think that might be?
