The report referenced in the previous exercise also gave responses to the question "What do you think is the best long-term investment?" by gender. Relative frequencies for the six response categories for men and for women are given in the accompanying table. $$\begin{array}{|lcc|}\hline \text { Response } & \text { Relative Frequency } & \text { Relative Frequency } \\ \text { for Women } & \text { for Men } \\\hline \text { Real Estate } & 0.33 & 0.32 \\\text { Stocks \& Mutual } & 0.21 & 0.25 \\\text { Funds } & & \\\text { Gold } & 0.14 & 0.22 \\\text { Savings } & 0.18 & 0.12 \\\text { Bonds } & 0.08 & 0.05 \\\text { Other } & 0.06 & 0.04 \\\hline\end{array}$$ a. Construct a comparative bar chart that shows the distributions of responses for men and for women. (Hint: See Example 2.4 . There should be two bars for each of the six response categories.) b. Comment on similarities and differences in the response distributions for men and women.

Key Concepts

Data Interpretation and Comparison

Data interpretation and comparison in this context involve analyzing the similarities and differences in the distribution of responses between two groups. This concept emphasizes not only processing the raw data presented as relative frequencies but also drawing meaningful conclusions about trends, preferences, or patterns that emerge from the comparison across the groups.

Categorical Data Analysis

Categorical data analysis involves examining data that is grouped into categories, such as responses to survey questions. This type of analysis focuses on understanding the distribution across the different categories and often employs visualizations like bar charts to aid in the interpretation of how each group responds.

Relative Frequency

Relative frequency represents the proportion of the total number of observations that fall into a particular category. It is calculated by dividing the count in a category by the overall total count. In the context of survey data, it allows comparisons of responses independent of the total sample sizes and helps in understanding the distribution of responses.

Comparative Bar Chart

A comparative bar chart is a type of graph used to visually compare the frequency or proportion of different categories across two or more groups. This chart displays bars side-by-side for each category, which allows observers to quickly assess similarities and differences in how the groups are distributed over those categories.
