Find the mode of the following data.Class interval0−100100−200200−300300−400400−500Frequency7111598
Modal Class (class with highest frequency) is 200-300.
Using Mode=l+(f1−f02f1−f0−f2)×h
where f1 represents the frequency of the modal class.
Also,
l= lower boundary of the modal class
h= size of the modal class interval
f0= frequency of the class preceding the modal class
f2= frequency of the class succeeding the modal class
Mode=200+15−1130−11−9×100
∴Mode=240
