A researcher compares the ethnicity of individuals in an experiment and whether they are in the treatment group or control group. Choose all the following tables and diagrams that would be appropriate ways to describe this data. Select all that apply. A. two-way table B. relative frequency bar graph C. frequency bar graph D. frequency table E. multiple bar graph F. pie chart G. relative frequency table

The appropriate ways to describe the data are:<br /><br />**A. two-way table** <br />**B. relative frequency bar graph** <br />**C. frequency bar graph** <br />**E. multiple bar graph** <br />**G. relative frequency table**<br /><br />### Explanation:<br />- A **two-way table** is suitable for comparing two categorical variables, such as ethnicity and group assignment (treatment or control). <br />- A **relative frequency bar graph** and a **frequency bar graph** can visually represent the distribution of individuals across categories. <br />- A **multiple bar graph** allows comparison of frequencies or relative frequencies across groups (e.g., treatment vs. control) for each ethnicity. <br />- A **relative frequency table** provides proportions or percentages, which are useful for understanding the relationship between the variables.<br /><br />### Not included:<br />- **D. frequency table**: While it can describe one variable, it does not capture the relationship between two variables like ethnicity and group assignment. <br />- **F. pie chart**: Pie charts are not ideal for comparing two categorical variables simultaneously.
