In order to draw a histogram, which axis is labeled with frequency?

In a histogram, the vertical axis is labeled with frequency. This axis represents the number of occurrences or frequency count of the values that fall within specified ranges or bins on the horizontal axis. The horizontal axis typically displays the ranges of data or categories, while the frequency reflects how many data points fall into each of those ranges. By visualizing this relationship, a histogram effectively communicates the distribution and frequency of data points in a dataset, allowing for insights into patterns, trends, and potential outliers.
