Question

The mean of the median, mode and range the observations 6, 6, 9, 14, 8, 9, 9, 8 is
a) 10.5 b) 8.5 c) 8.8 d) 10.3

Answer 1

Answer:

8.5

Step-by-step explanation:

Given,

6 ,6 ,9 ,14 ,8, 9,9,8

Median:

According to the data arrange it in ascending order: 6,6,8,8,9,9,9,14

=Median = 4th term+ 5th term ÷ 2

Therefore , median= 8+9÷2 = 8.5.

Mode:

Since the frequent number in the data is 9 which is occurring three times,then

Mode = 9.

Range:

The largest value is 14 and the smallest value is 6.

Range = 14-6 = 8.

Hence, the required mean = 8.5 + 9 + 8 ÷3

= 25.5 ÷3

= 8.5
