how much individual scores differ from the mean (average)
Which of the three measures of central tendency is most easily distorted by a few very high or very low scores?
mean (average)
“How can regression toward the mean influence our interpretation of events?”
Regression toward the mean is a statistical phenomenon describing the tendency of extreme scores or outcomes to return to normal after an unusual event. Without knowing this, we may inaccurately decide the return to normal was a result of our own behavior.
knowing two events are correlated provides…
