PSYC35H3 Lecture Notes - Conscientiousness, Effect Size, Extraversion And Introversion
Document Summary
Structure: relatively consistent (stable) pattern of correlated relationship seen in variables. There is a review paper by dan ozer and he says that individual difference is significant. There"s a practical importance in labs, but not only in here but also in real life settings. The goal of personality is to show that this is important for life outcomes. There are proofs from 2 reviews: 1. People have underestimated personality correlation-standardized index of the degree of association between two variables. The correlation always has direction and magnitude( size, + or -) A perfect correlation is -1 or +1, so this is the range. The larger the number, the stronger the degree of relationship. Effect size: size of the relationship, the larger the correlation the larger the effect size. Correlation: r= 0. 10 is small, r=0. 30 is medium, r=0. 50 is large. 2 bias source: it is easy for us to think of variables as perfect correlations, but these are never seen in nature.
