Here is a set of data: 1, 1, 2, 2, 2, 3, 3, 3, 4, 5, 6, 6, 6, 6, 6, 7, 7, 9, 9, 9, 9, 9, 10, 10, 11, 12, 13, 14, 14, 15 1) Please pick intervals and make a chart to count how many scores fall in each interval (please include cumulative frequency, relative frequency, relative percent, cumulative relative frequency, and cumulative relative percent).

2) Next, draw a histogram for continuous data from these scores and then add lines to make a frequency polygon.

Here is a set of categorical data: Hispanics: 20 African Americans: 40 Whites: 50 Asians: 10

1) Make a bar graph for categorical data based on this information.

2) Make a pie chart by computing the central angles of this data.

3) Practice computing the means for these lists of data: a. 1, 3, 5 b. 5, 6, 7, 7, 15 c. 7, 8, 9, 10 d. 50, 100, 150 e. 1, 3, 300

4) List the letters (use all) where the mean that would (a) best represent the list of scores and (b) least represent the list of scores.
