Option 2 : Median is greater than the mean
Given:
The series of the scores 15, 8, 13, 1, 23, 15, 20, 1
Formula used:
Mean = Sum of terms/Total number of terms
Median of data depends on the number of observations (n)
If number of observation is odd then
Median = Value of th observation
If number of observation is even then
Median = (1/2) × value of observation
Calculation:
The series of the scores 15, 8, 13, 1, 23, 15, 20, 1
Mean = (15 + 8 + 13 + 1 + 23 + 15 + 20 + 1)/8 = 96/8 = 12
There are two numbers 1 and 23 at the middle of the series. Then the median will be the average of these two numbers.
Arrange the given data in ascending order 1, 1, 8, 13, 15, 15, 20, 23
Here n = 8 which is even
Median = (1/2) × value of observation
⇒ (13 + 15)/2
⇒ 14
∴ Median is greater than the mean
Hence, option 2 is correct.
