Conditional Variance Example Calculation

Conditional Variance Example Calculation. Variance analysis is calculated using the formula given below. In terms of the scatter plot, the familiar quantity v a r ( y) = e ( ( y − e ( y)) 2) is the mean squared distance between the points and the horizontal line at level e ( y).

In terms of the scatter plot, the familiar quantity v a r ( y) = e ( ( y − e ( y)) 2) is the mean squared distance between the points and the horizontal line at level e ( y). By definition, the conditional probability equals the probability of the intersection of events a and b over the probability of event b.
