Compute the mode of the following distribution:
Class interval | ||||||
Frequency |
Step 1: Finding different values of mode formula
Given table:
Class interval | ||||||
Frequency |
From the above table, we can see that the class has a maximum frequency, so the modal class is .
For determining the mode we will use the formula:
Where, = Lower limit of modal class
= Size of the class-interval
= Frequency of the modal class
= Frequency of the class preceding the modal class
= Frequency of the class succeeding the modal class
Step 2: Finding the mode
Substituting the values in the mode formula:
Hence, the mode of distribution is .
