If everyone in the population has an å score of zero,then the variance of the å scores
across individuals is also zero,and Y is a perfect linear function of X.

Question

Quizplus · Accepted Answer

If everyone in the population has an å score of zero, then the deviation of each individual score from the mean (i.e. the variance) is zero. This means that all individuals have the same å score and the relationship between X and Y is perfectly linear, as there is no variation in the data. Therefore, the statement is true.

If Everyone in the Population Has an å Score of Zero,then
