Read through the scenario below and answer the following questions.

The following data set is from a survey of the weekly number of hours spent exercising for 40 high school students.

8	10	14	3	11	9	11	5	11	17
13	11	9	13	6	8	10	15	3	10
13	12	15	13	12	5	1	7	5	7
9	5	5	10	9	12	2	7	6	8

Ungrouped Data Set

1. Order the data set and determine the mean, median and mode.

Grouped Data Set

1. Calculate the bin width that will divide the data into 5 intervals. Show your calculations in a Word or WordPerfect document.
2. Complete the frequency distribution table using the bin width calculated in question 1 and copy it into a Word or WordPerfect document.

Interval	Midpoint	Tally	Frequency	Relative Frequency	Cumulative Frequency

1. Produce a histogram of the data set using Fathom or by hand and copy and paste it into the Word or Word Perfect Document.
2. Determine the mean interval, median interval and modal interval for grouped data.
3. Discuss the difference between the values for central tendency obtained for the ungrouped versus the grouped data set. In particular, compare the mode and the modal intervalwhich is a better measurement?
4. What can you conclude about the given data set?
