PSYC35H3 Lecture Notes - Lecture 10: Statistical Power, Time Point, Ipsative
Document Summary
Industrialized societies afford people between the ages of 18 and 26 to reach immerging adulthood; a period where you can reflect on your own development and create your own person. There are large changes in demographics for people within this time span. We are looking for continuity and change within this period. Maturity is known as the period of time where your body does not undergo very many changes because it doesn"t need to. Differs in three regards (are all overcome in the dunedin study: nature of sampling. We sample by convenience, usually university students: low statistical power. We lower the participant sample sizes and this lowers the statistical power to detect the effects we are interested in: failure to broadly sample the desire of interest. We narrow things down to a few traits and ignore other traits. Very few studies have looked at all traits longitudinally and simultaneously.
