Document Summary

Psychology as a science: scientific theories are used to form hypotheses, which are then empirically tested through systematic observation. Hypotheses: are testable, are based on prior theory/ research, describe relationships between variables (if x then y ). The theoretical population who you want to generalize to. The study population the population for which you can gain access. The sampling frame the procedure by which you plan to access the population. The sample who is actually in your study. Representative sample having the same characteristics as the population. Random selection the selection process is random. When a concept is measured in a concrete manner it becomes a variable that can take on multiple values. Variables can be measured based on: physiological markers, behavioural measures, observation, self-reported surveys, ratings from others. Types of variables: in an if x, then y statement: X is the predictor or independent variable. Y is the outcome of dependent variable.
