1. The following table shows the ages of the patients admitted in a hospital during a year:
Find the mode and the mean of the data given above. Compare and interpret the two measures of central tendency.
The class having maximum frequency is the modal class.
The maximum frequency is 23 and hence the modal class = 35-45
Lower limit (l) of modal class = 35, class size (h) = 10
Frequency ( ) of the modal class = 23, frequency ( ) of class preceding the modal class = 21, frequency ( ) of class succeeding the modal class = 14.
The maximum number of patients are in the age group of 36.8, whereas the average age of all the patients is 35.37.
