Document Summary

3 essential elements (a) testable & falsifiable (b) based on wide range of evidence & repeatedly verified. Hypothesis: relatively narrow explanation for a phenomenon that emerges" from a theory (a) testable & falsifiable (b) based on limited evidence. Research: systematic collection of data, aimed towards testing a hypothesis. 5 types of designs: descriptive: observing & noting behavior of people/animals to provide systematic & objective analysis of behavior, observational studies, naturalistic observations passive involvement. Disadvantages little control observer bias b. developmental designs i. longitudinal design: observing & classifying developmental changes that occur in same people over time. Advantages effects of age see developmental changes differences ii. cross -sectional design: observing & classifying developmental that occur in different groups of people at the same time. Correlational: how variable are naturally related in the real world: correlation coefficient: statistic between -1. 0 & 1. 0 indicating strength of relationship between variables.
