**Problems**

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

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

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

*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.)

*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)

c. frequency polygon

d. ojive - The abscissa refers to

a. a type of graph used for metric data

b. the x-axis of a graph
