A researcher analyzed the results of her data and calculated the standard deviation of scores at 3.5. what is the variance?
Solution: We are given the standard deviation of scores = 3.5
We know that the variance is the square of the standard deviation.
Therefore, the variance is:
[tex] Variance = (Standard-deviation)^{2} [/tex]
[tex] =3.5^{2} [/tex]
[tex] =12.25[/tex]
Therefore, the variance of the scores is 12.25
