Document Summary
Reliance on real evidence to confirm or refute claims. Findings must be replicated before they are accepted. Hypotheses and theories must be falsifiable/refutable through empirical research. Simplest explanation for a phenomena: psychology is a science because when researching we use the scientific method, the science of psychology provides the theory. The two ingredients that make a true experiments are random sampling from the population under study and random assignment to the experimental groups. 3. cross-sectional research studies individuals of different ages at a given point in time, and a longitudinal research studies a single age cohort over along period of time. The cohort is a variable that influences both the dependent variable and independent variable causing a spurious association: the abstract is a brief summary of what will happen in the study. 150-200 words long so it is just a brief overview of everything in the study. The introduction is untitled and comes after the abstract.
