Question
There is a football team named Mad Max. The following data shows a score of the
Mad Max team in their regional matches.
20 , 15 , 16 , 25 ,10 , 5 , 6 , 12
What is the standard deviation of the given data?
- 6.99
- 7.99
- 5.99
- None of these
Hint:
In this question, we have to find the standard deviation of the data given. We know that standard deviation is 
. And variation = 
, where n = number of terms, 
= is the data, 
= mean. Using this formula, we will find the standard deviation.
The correct answer is: 5.99
The mean of the data is 13.625
