What type of graphical representation is used to display a frequency distribution?

• A. Line Graph
• B. Bar Chart
• C. Histogram
• D. Pie Chart

Answer: (C)

A histogram is the appropriate graphical representation for illustrating a frequency distribution because it displays the distribution of numerical data. In a histogram, data is divided into intervals or "bins," and the frequency of data points within each interval is represented by the height of the corresponding bar. This allows for a clear visual understanding of how data is distributed across various ranges, highlighting trends and patterns effectively. Unlike other graphical forms, such as a line graph, which is often used for displaying trends over time, or a pie chart, which depicts parts of a whole, a histogram specifically focuses on the distribution of continuous data. The bar chart is similar but is generally better suited for categorical data rather than for showing the underlying frequency of numerical data in specific ranges. Therefore, when aiming to convey the distribution of a dataset, a histogram is the ideal choice.
