COMPLETE Intro Psychology Course - ALL TOPICS - IQ Variation & Distribution (Intro Psych Tutorial #118)

www.psychexamreview.com In this video I describe variation in IQ scores and the distribution of IQ scores in the general population. IQ scores follow a normal distribution with a mean of 100 and a standard deviation of about 15 points. Knowing IQ follows a normal distribution allows us to estimate percentile scores for IQ and see how a particular score compares with all other scores. Intellectual giftedness (IQ scores around 130 and above) is associated with a number of positive life outcomes including greater longevity, while ‌intellectual disability (IQ scores below 70) is associated with difficulties completing routine daily tasks and inability to lead an indepedent life.
