Answer: b.

15. The frequency distribution graph appropriate for scores measured on a nominal scale is only a bar graph. This is because if data is from ordinal or nominal, the graph is constructed with spaces in between. Therefore, a polygon and histogram do not have spaces in between values or bars.
Answer: d.
21. The frequency distribution graph that shows the frequencies as bars that are separated by spaces is a bar graph.
Answer: a.

25. The term that is used to describe the shape of distribution in which the scores pile up on the left-hand side of the graph and taper off to the right ispositively skewed.
Answer: b.
