The median is the middle value of a data set, which may or may not fall in the midpoint of a class interval. The mode is the most frequently occurring value in a data set, and it may or may not be located in the midpoint of a class interval. The histogram is a graphical representation of the distribution of a data set, which uses adjacent rectangles to show the frequency of observations within each class interval.
