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 =
$\sqrt(Variance)$

Substituting the value of Variance, to evaluate the standard deviation.

We get,

Standard deviation =
$\sqrt(14.94)$

= 3.865

= 3.87

Therefore, the standard deviation is 3.87
