Question
n order to calculate the variance of a sample of scores... Type II errors must be avoided acceptable levels of covariance must be established with similar measures you should square the standard deviation you could estimate based on previous similar studies
Solution 1
To calculate the variance of a sample of scores, you should square the standard deviation. Variance is a statistical measurement of the spread between numbers in a data set. More specifically, variance measures how far each number in the set is from the mean (average) and thus from every other number in the set. Variance is often denoted by the symbol σ^2. It is used by both analysts and traders. The square root of the variance is the standard deviation (σ), which helps determine the consistency of an investment's returns.
