Collect 50 or more quantitative data.

a.) Using StatCrunch, compute the following five summary statistics:

• Sample mean
• median sample
• standard deviation
• range
• interquartile range (IQR)

TheTechnology Step-by-Stepbox at the end of Section 3.1 (page 130 in your textbook) explains how to do summary statistics using StatCrunch. Do not forget the video explanation in the Module Notes, if you need it.

b.) Then, construct a histogram, as in Module 1. Recall, theTechnology Step-by-Stepbox at the end of Section 2.2 (before the end-of-section problems) explains how to histogram using StatCrunch. This time, you do not have to construct a histogram with sliders. For an example of the steps taken and what to expect,click here.

Make sure your data set is large enough (50 items).

c.) Then, answer the following two questions:

• Looking at your data and the histogram, which measure of central tendency (mean or median) best describes the "center" of the distribution? For ideas, the end of Section 3.1 provides a summary.
• Looking at your data and the histogram, which measure (sample standard deviation, range, or interquartile range) best describes the "dispersion" of the distribution? For ideas, page 158 in Section 3.4 provides a summary.
