Document Summary
What is good research: helps reach well founded conclusions. Maximize how much what you manipulate leads to results: able to be replicated and translated. Basic components of research: research question. How can we help them develop more adaptive behaviors: hypothesis. Need to be able to test them. Altered hypothesis: college students who exercise are happier: independent variable: exercise, dependent variable: happiness, population: college students. Extensive observation and detailed description of a single client. Foundation of early historic developments in psychopathology. External validity is typically weak: correlational research. Assess the degree to which levels of certain variables are linked to levels of other variables. Example: higher levels of education are linked to higher levels of income. Statistical relation between two or more variables. Range from -1. 0 to 0 to +1. 0: negative vs positive correlation. Correlation is not causation: experimental designs. Premium on internal validity: randomized controlled trials. Involves manipulating a variable (introducing or withdrawing something in a controlled way)
