What is the mode of distribution for the given list?

Marks	4	5	6	7	8
No. of students	6	7	10	8	3

A. 5
B. 6
C. 8
D. 10

Hint: First we will find the number of students who get the same marks from the list. The maximum frequency of the marks is the mode.

Formula Used:
The value that repeatedly appears in a given set is called the mode.
The quantity of occurrences of an event in an experiment is its frequency (or absolute frequency).

Complete step by step solution:
Find the frequency of each mark.
The frequency of mark 4 is 6.
The frequency of mark 5 is 7.
The frequency of mark 6 is 10.
The frequency of mark 7 is 8.
The frequency of mark 8 is 3.
The maximum frequency is marked as 6.
Thus, the mode of distribution for the given list is 6.

Hence the correct option is B.

Additional Information:
Frequency: The number of times that observations are occurred is known the frequency.
If a set has 2 modes then the set is known as bimodal. If a set has 3 modes then the set is known as trimodal.
If a set has more than one mode, then the set is known as multimodal.

Note: Sometimes the mode of the object is equal to the mean but it doesn't always happen. The object that appears maximum times is known as a mode.
