A histogram is used primarily to show which aspect of data?

• A. Frequency distribution
• B. Central tendency
• C. Range
• D. Scatter relation

Answer: (A)

Histograms illustrate how data values are spread across different value ranges. Each bar represents a bin, and the height shows how many observations fall into that bin, i.e., the frequency. This setup makes the frequency distribution of the data immediately visible—the pattern of counts across the range, where values cluster, whether the data are skewed, and whether there are multiple peaks. While you can get a rough sense of the center or the overall spread from the shape, those aren’t the primary purpose of a histogram. Central tendency would be described by a single value like the mean or median, which a histogram doesn’t directly provide. The exact min and max (the range) can be inferred from the ends of the distribution, but a histogram isn’t primarily used to quantify range. A scatter plot, by contrast, shows the relationship between two variables, which is not what a histogram is designed to convey.
