Homework - Graphing

Problems

Using the numerous rules discussed in class (e.g., each graph goes on a separate page), create each of the following graphs. You can do them by hand using graph paper (or, if you know how, with a computer program like MS Excel). In either case, to make the grading of the project easier and more straight forward, it must be printed (in other words, it cannot be handed in electronically).

1. A bar graph of fictitious data which is measured on a categorical scale (18 points).

2. A bar graph of fictitious data which is measured on a ordinal scale (18 points).

3. Histogram for the data in Question 2 of the homework on frequency distributions (18 points).

4. Frequency polygon for data in Question 3 of the homework on frequency distributions (18 points). (Be careful to use the correct data to graph your points.)

5. Bar graph for data in Question 2 of the homework on research design (18 points). Note that you will need to make up some data here (i.e., the individual scores & do provide these) and then compute the averages for each group. The averages are what belong in the graph. To keep things simple, assume there are 5 subjects per group.

Multiple Choice (10 points)

2. The abscissa refers to
