Question

The mean of the median , mode and range of the observation 6, 6, 9, 14,8,9,9,8

Answer 1

In ascending order the numbers are 6,6,8,8,9,9,9,14.

The Mean

x¯¯¯=∑xN

Here,
∑ represents the summation
X represents scores
N represents number of scores.

Hence, the mean is 8.625

The Median: If the total number of the numbers(n) is an even number, then the formula is given below:

Median=(n2)thterm+(n2+1)thterm2

Hence , the median is 8.5

The Mode: The mode is the most frequently occuring score or value.

Hence, the mode is 9.

Answer 2

arrange as ascending order

6 6 8 8 9 9 14

mean = <6+6+8+8+9+9+14>/7

mode =8

median = most repeated =6 or8 or 9
