PS101 Lecture Notes - Standard Deviation, Percentile, Emor
Document Summary
Psychologists + scientists share 3 sets of interrelated goals: measurement + description: requires that an investigator figure out a way to measure the phenomenon under study, develop measuring techniques that make it possible to describe behaviour precisely. To evaluate their understanding, scientists make and test predictions called hypotheses. Hypothesis: a tentative statement about the relationship between two or more variables. Variables: are any measurable conditions, events, characteristics or behaviours that are controlled or observed in study: application + control: scientists hope the information they gather will be of some practical value in helping solve everyday problems. Clinical psychologist might use what we know about typical everyday emotions to help individuals suffering from emotional disorders. Theory: is a system of interrelated ideas used to explain a set of observations. Psychologists use theories not just isolated facts to get a better understanding of behaviour.
