What statistical measurement reflects the distribution of data across various categories?

The histogram is a statistical measurement that visually represents the distribution of data across various categories by using bars to illustrate the frequency of data points within specified ranges or bins. Each bar corresponds to a category or interval, and the height of the bar indicates the number of observations in that category. This makes histograms particularly useful for understanding the shape and spread of the data, allowing analysts to identify patterns such as normal distribution, skewness, or the presence of outliers.

The other options do not serve the same function: impact typically refers to the effect of a variable rather than a visual representation of distribution; hypothesis pertains to a testable prediction in research rather than a measure of data distribution; and input generally relates to data entering a system but does not specifically address how that data is distributed across categories.
