What does a Histogram display?

A histogram is a specific type of bar chart that represents the frequency distribution of numeric data. In a histogram, the data is divided into intervals or "bins," and the height of each bar reflects the number of data points that fall within each interval. This visual representation allows for an immediate understanding of the data's distribution, including aspects such as central tendency, variability, and the presence of any outliers or skewness.

The other options refer to different types of data visualization or analysis. Geographical data trends would typically be displayed using maps or geospatial charts, while qualitative data categories may be best represented through pie charts or categorical bar charts. Process performance over time is more commonly shown using line graphs or control charts that track changes across different time points. Therefore, the characteristic of a histogram specifically pertains to its ability to visually depict numeric data through the use of bars, making this the correct answer.
