Since, the variance calculated on 34 scores is equal to 14.94.
We have to determine the standard deviation.
Relationship between Variance and standard deviation is:
Standard deviation = [tex]\sqrt(Variance)[/tex]
Substituting the value of Variance, to evaluate the standard deviation.
We get,
Standard deviation = [tex]\sqrt(14.94)[/tex]
= 3.865
= 3.87
Therefore, the standard deviation is 3.87
