Breaking Down the Problem

To determine the best way to present categorical data, we need to analyze the options provided.

Relevant Concepts

1. Categorical Data: This type of data represents characteristics and can be divided into categories. Common types include nominal (names or labels) and ordinal (a ranked order).

2. Visualization Techniques:

   • Bar Chart: Displays categories with rectangular bars; suitable for comparing different groups.
   • Pie Chart: Represents proportional parts of a whole; effective for showing relative sizes of categories.
   • Box Plot: Shows the distribution of quantitative data but is not ideal for categorical data.
   • Histogram: Used for continuous data, it is not suitable for categorical data.

Analysis and Detail

1. Option a (Bar chart or pie chart): Both are effective for categorical data. Bar charts can show comparisons across categories nicely, while pie charts illustrate parts of a whole.

2. Option b (Box plot or histogram): Neither is suitable for presenting categorical data as both are meant for quantitative data.

3. Option c (Histogram or pie chart): The histogram is inappropriate as it deals with continuous data.

4. Option d (Box plot or pie chart): The box plot is not effective for categorical data, leaving only the pie chart without a suitable alternative.

Verify and Summarize

The best options for displaying categorical data are bar charts and pie charts, making option (a) the correct choice.

Final Answer

a. Bar chart or pie chart
