Which chart is commonly used to illustrate the distribution of survey results?

A histogram is specifically designed to illustrate the distribution of data points across various ranges or intervals, making it particularly effective for displaying survey results. It allows for a visual representation of how many responses fall within specified categories, helping to identify patterns, trends, or outliers in the data set. By grouping the survey results into bins or intervals, a histogram provides insights into how responses are distributed, such as whether they are skewed towards one side, uniform, or normally distributed.

In contrast, line charts are typically used for showing trends over time and may not effectively display the distribution of categorical survey data. Pie charts serve to represent proportions of a whole, which is useful for understanding the share of individual categories but not ideal for showing the frequency distribution of responses. Vertical bar charts can also show categorical data, but they are better suited for comparing discrete categories rather than illustrating the distribution of data across ranges, which is the core function of a histogram.
