How does the histogram function illustrate the usage of data values?

The histogram function effectively illustrates the usage of data values by showing the sample frequency distribution. It visually represents how many times each range of data values occurs within a dataset. Each bar in a histogram corresponds to a specific range (or bin) of values, and the height of the bar indicates the frequency of data points that fall within that range. This allows for a quick visual assessment of the distribution pattern of the data—such as whether it is normally distributed, skewed, or contains outliers—enabling analysts to make informed decisions based on the data.

In contrast, displaying statistical forecasts or calculating averages represents different analytical functions that do not offer a direct visual representation of how data is distributed across various value ranges. Summing total values provides a cumulative amount rather than a distribution representation, which is crucial for understanding data trends and behaviors comprehensively.
