Title: Bacis Statistics Histogram

Histogram is a graphical display of the data distribution between non-overlapping intervals within the range of the data consisting of the count (or number) of values that fall into each interval.

January Tmax Histogram
Figure 1. Histogram of January Tmax at Central Park, NY. Each temperature bin is 2 degrees F. Height of the bars equals the number of observations that fall in each 2 degree temperature interval.

These counts can be divided by the total number to give a relative frequency of occurrence. Bars are plotted with height proportional to the relative frequencies.
