Document Summary
Life outcomes: what has happened in your life. Behavioral observations: let me see what you do, naturalistic & performance measures. Reliability: the degree to which a test produces the same results when given under the same conditions ~ consistency. Validity: the extent to which a test measures what it intends to measure. A test can be highly reliable, but not at all valid. A test cannot be valid if it is not reliable. Correlational approach: correlation coefficient (r) measures strength of relationship between 2 variables (range: -1. 00 to +1. 00) Experimental approach: research technique that establishes causal relationship between independent variable & dependent variable by randomly assigning participants to experimental groups. Test differences between groups with statistical tests to determine if the difference is larger than would be expected by chance. Correlational: there is no relationship between the variables. Experimental: the experiment manipulation has no effect on the dependent variables.
