To find the median class in a histogram, we need to identify the class interval that contains the median value. The median is the middle value in a dataset, so we need to find the midpoint of the data.
To find the median class:
1. Add up the frequencies in the histogram starting from the left-hand side until the total is greater than or equal to the total number of data points divided by 2.
2. The median class is the class interval that contains the midpoint of the data.
In this histogram, the total number of data points is 80. The midpoint is (80 + 1)/2 = 40.5.
Starting from the left-hand side, we can add up the frequencies: 8 + 19 + 24 = 51. The median falls within the interval 40.5 - 50.5, which is the third interval.
Therefore, the median class is 40.5 - 50.5.
