Research strategy: the general approach to research determined by the kind of question that the research study hopes to answer. To be a true experiment and therefore cannot determine. No matter which design you use in your research, good research always begins with a random selection of participants. A variable is something that varies so it must have at least 2 levels or values. Scientists examine the causal relationship between variables in an experiment by manipulation, controlling and measuring variables. Is the manipulated variable in an experimental model. Is the measured variable in an experimental model (quantitative in this course) Is the variable that is kept constant across the independent variable so that it does not become a . Is a variable that adversely affects the dependent variable in a manner you do not want it to do.
