Question 1: Find out the mode of the following marks obtained by 15 students in a class:
Marks: 4, 6, 5, 7, 9, 8, 10, 4, 7, 6, 5, 9, 8, 7, 7.
Solution:
Mode is the value which occurs most frequently in a set of observations.
The frequency of the given set of observations is as given below:
Here, we can see that 7 occurred most frequently.
So, Mode = 7
Question 2: Find out the mode from the following data :
125, 175, 225, 125, 225, 175, 325, 125, 375, 225, 125
Solution:
Find the frequency of the given set of observations:
125 occurred 4 times more than any other values.
So, Mode = 125
Question 3: Find the mode for the following series:
7.5, 7.3, 7.2, 7.2, 7.4, 7.7, 7.7, 7.5, 7.3, 7.2, 7.6, 7.2
Solution:
Find the frequency:
Maximum frequency 4 corresponds to the value 7.2.
So, mode = 7.2
