Analysis of the Question

1. Understanding Histograms: Histograms are graphical representations of the distribution of numerical data. They display the frequency of data points within certain ranges (bins).

2. Types of Data:

   • Numerical Data: This includes any data that is quantifiable, such as height, weight, or temperature.
   • Categorical Data: This consists of data that can be divided into groups or categories, like colors or brands.

3. Purpose of a Histogram: Histograms are particularly useful for illustrating the distribution of numerical data to understand its shape, central tendency, and variability.

Verification of Options

• Option a: "numerical and categorical data" - Incorrect as histograms do not effectively represent categorical data.
• Option b: "just numerical data" - Correct since histograms are designed to display distributions of numerical data.
• Option c: "just categorical data" - Incorrect as histograms are not suited for categorical data alone.
• Option d: "numerical or categorical data" - Incorrect because histograms are predominantly for numerical data.

Conclusion

Based on the understanding and analysis of histograms and the types of data they represent, the best choice is:

Final Answer

b. just numerical data
