Structure: relatively consistent (stable) pattern of correlated relationship
seen in variables
- individual differences matter and are consequencial.
- There is a review paper by Dan Ozer and he says that individual difference
Practical Importance of Personality
-There's a practical importance in labs, but not only in here but also in real
- The goal of personality is to show that this is important for life outcomes
- There are proofs from 2 reviews: 1. Dan Ozer(narrative) 2. Brent Roberts
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
- Validity coefficients: ( Look up)
Correlation: r= 0.10 is small, r=0.30 is medium, r=0.50 is large
- 2 bias source:
1. It is easy for us to think of variables as perfect correlations, but these are
never seen in nature. Therefore we tend to want larger correlations....
2. There are two kinds of correlations:
b. reliability coefficient: Which is how well does a measure correlate with itse
