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 =
![√(variance)](https://img.qammunity.org/2021/formulas/mathematics/college/pder7snwmsnd1e0zs0v9onx9qpxc1ok0da.png)
=
![√(113)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/uhthrkfalcahekfexb2d5w0ml33q6movmg.png)
= 10.63
Therefore for computing the standard deviation we simply applied the above formula.
