Question

What is the main difference between a histogram and a bar chart?

• A. A histogram is used for discrete data while a bar chart is used for continuous data.
• B. A histogram is used for continuous data while a bar chart is used for discrete data.
• C. A histogram has classes of equal width, while a bar chart has classes of varying width.
• D. A histogram is used for categorical data, while a bar chart is used for numerical data.

Answer 1

Answer:

B. A histogram is used for continuous data while a bar chart is used for discrete data.

Correct answer is option B

The core difference between these two charts is the nature of the data they represent:

1. Histogram (Continuous Data): Used for data that can be measured on a scale and can take any value (like height or time). This is why the bars touch—they represent a continuous range of numbers.

2. Bar Chart (Discrete Data): Used for distinct categories or "countable" numbers (like types of pets or number of siblings). There are gaps between the bars because the categories are separate and not connected.
