Answer:
9.4
Step-by-step explanation:
Answer:
10.63
Step-by-step explanation:
Data provided in the question
Data = 30 subjects
The Variance of scores = 113.00
The calculation of standard deviation is shown below:-
As we know that
Variance = Standard deviation^2
Therefore,
Standard deviation = 
= 
= 10.63
Therefore for computing the standard deviation we simply applied the above formula.
