Question

Quizplus · Accepted Answer

The regression equation measures how far each data point deviates from the line that most closely fits the data. It is used to predict the value of one variable based on the value of another variable. It does not measure the deviation of the sample mean from the population mean, the significance of mean differences between groups, or the frequency of scores regressing from deviations in the data.
