Document Summary

Describe and provide examples of the four sources of data (discuss strengths & weaknesses; possible links between them) How do we evaluate personality measures? (reliability, validity, generalizability) A theory is a set of statements designed to explain how the world works. A hypothesis is a statement of what you think should happened in your experiment. Correlational studies (observation & measurement without manipulation) This can refer to traits that each person can exhibit to a different level (i. e. traits such as self- concept are generally considered to be fairly stable, but will be different from one person to the next). This can also refer to characteristics that can fluctuate (i. e. emotions such as happiness). Independent variable (iv) in an experimental design, this is the variable that is actively manipulated by the researcher. Dependent variable (dv) in an experimental design, this is the variable that is measured.
