Question

What two types of graphs are most common when the categories are qualitative​ data? Describe the construction of each.

Select the two choices below that correctly answer the question above.


A. In a pie​ chart, each category corresponds to a wedge of a circle. The size of each wedge is proportional to the relative frequency of the category it represents.

B. A frequency table has two columns. The first column lists all of the categories of data. The second column lists the frequency of each category.

C. In a bar​ graph, each category corresponds to a wedge of a circle. The size of each wedge is proportional to the relative frequency of the category it represents.

D. In a pie​ chart, the categories are clearly indicated along the horizontal axis. Over each category is a rectangle whose height indicates the frequency or relative frequency of the category. Numbers along the vertical axis clearly indicate the scale.

E. In a bar​ graph, the categories are clearly indicated along the horizontal axis. Over each category is a rectangle whose height indicates the frequency or relative frequency of the category. Numbers along the vertical axis clearly indicate the scale.

F. In a frequency​ table, each category corresponds to a wedge of a circle. The size of each wedge is proportional to the relative frequency of the category it represents.

Answer 1

A. Pie charts - in a pie chart, each category corresponds to a wedge of a circle. The size of each wedge is proportional to the relative frequency of the category it represents.

E. Bar graphs - in a bar graph, the categories are clearly indicated along the horizontal axis. Over each category is a rectangle whose height indicates the frequency or relative frequency of the category. Numbers along the vertical axis clearly indicate the scale.

Answer 2

Step-by-step explanation:

A. Pie charts - in a pie chart, each category corresponds to a wedge of a circle. The size of each wedge is proportional to the relative frequency of the category it represents.

E. Bar graphs - in a bar graph, the categories are clearly indicated along the horizontal axis. Over each category is a rectangle whose height indicates the frequency or relative frequency of the category. Numbers along the vertical axis clearly indicate the scale.
