A histogram is primarily used to display which of the following characteristics of a data set?

• A. Frequency of occurrences
• B. Median value
• C. Correlation between variables
• D. Cumulative probability

Answer: (A)

Histograms show how data are distributed across intervals. The height of each bar represents how many observations fall into that range (or their relative frequency), so you can quickly see where data cluster, how spread out they are, and the overall shape—whether it’s skewed, symmetric, or has multiple clusters. This visualization highlights frequency across value ranges, which is different from a single central value like the median, and it isn’t used to examine relationships between two variables, which would require a scatter plot, nor is it a cumulative view like a cumulative probability plot.
