Solution Steps

To determine the two most common types of graphs for qualitative data, we need to identify the correct descriptions of these graphs. Qualitative data is typically represented using pie charts and bar graphs. A pie chart uses wedges to represent categories, with the size of each wedge proportional to the category's relative frequency. A bar graph uses rectangles to represent categories, with the height of each rectangle indicating the frequency or relative frequency.

Step 1: Identify the Graph Types

The two most common types of graphs for qualitative data are the pie chart and the bar graph.

Step 2: Describe the Pie Chart

A pie chart represents categories as wedges of a circle. The size of each wedge is proportional to the relative frequency of the category it represents. This can be expressed mathematically as: \[ \text{Wedge Size} = \frac{\text{Frequency of Category}}{\text{Total Frequency}} \times 360^\circ \]

Step 3: Describe the Bar Graph

A bar graph displays categories along the horizontal axis, with rectangles (bars) above each category. The height of each rectangle indicates the frequency or relative frequency of the category. Mathematically, this can be represented as: \[ \text{Height of Bar} = \frac{\text{Frequency of Category}}{\text{Total Frequency}} \times \text{Max Height} \]

Final Answer

The correct answers are C and D. Thus, the answer is: \[ \boxed{\text{C and D}} \]
