First steps: the goal of research is to explain and predict, ultimate goal is to answer a question, a research question can be answered in several ways, survey, random controlled trial, case-control study, etc. Questions to ask when critiqing a research study. Survey: a survey is a study that essentially asks people (subjects) questions that either generalize or explain trends in behavior, belief, etc. Experiment: an experiment aims to test an intervention to measure its impact, an experiment needs to control all variables except for the one its intending to measure. Independent variable: the variable that is changed between the control group and experimental group, dependent variables, the response that is measured due to the change in the dependent variable. Xamples of variables: a researcher wants to determine if the use of moist heat increases shoulder flexion range of motion.
