Question

if the mode of the following data is 7 find the value of x:
3, 5 ,6 ,7 ,5, 4, 7, 5 ,6, x + 1,8,7

Answer 1

We have,

3, 5, 6, 7, 5, 4, 7, 5, 6, x + 1, 8, 7

The mode is the value which occur maximum number of times,that is, the

mode has maximum frequency.

If the maximum frequency occurs for more than 1 value, then the number of

mode is more than 1 and is not unique.

Here it is given that the mode is 7.

So, x + 1 = 7 ⇒ x = 6
