Document Summary

Formal, objective, systematic process where numerical data is obtained. Descriptive- structured observations/survey, for phenomenon, situation or group. Exploratory- gain new insights, discover and increase knowledge about phenomenon (with little information on the topic) Casual- experimenting to assess cause and effect. Directs research process (who, what, when, where and how) Purpose: answer questions, understand biases, direct analysis, direct interpretation. Develop study to bridge gap for what is unknown. Literature review is crucial-ethical approval and funding. Objectively conceptualized- literature review reflect who what when where why. Feasible- large samples to answer question within time and funding. Control- control potential bias to give valid results. Externally valid- results are useful for other people/situations. Experimental: randomized control trials, quasi-experimental, pre-experimental. Non-experimental: descriptive (correlational, univariate, correlational (retrospective/prospective, natural, path analytical) There is an experimental and control group. Random assignment to groups (internal validity issue) Random selection from population to sample (external validity issue) Equal extraneous variables in sample that are true for population.
