The frequency histogram displays the frequencies of the classes on the vertical axis.
In more detail, a frequency histogram is a graphical representation used to display the distribution of numerical data. It visually summarizes the number of data points that fall within specific intervals or classes.
Here's a breakdown of how it works:
-
Horizontal Axis: Represents the classes or intervals of the data. These classes are mutually exclusive and cover the entire range of the data.
-
Vertical Axis: Represents the frequency (or count) of data points falling within each class. The higher the bar, the more data points fall within that specific interval.
Therefore, the height of each bar in the histogram corresponds to the number of observations within that particular class, providing a clear visual representation of the data's distribution. The vertical axis is critical for understanding how often data points occur within the defined categories.
