Valid Measurement Reliability Content/Convergent/Discriminant Validity Assessment
Research Questionnaire: Practice 1 For your proposed study, specify the dependent variable(s) and the independent variables. To collect data for your study, which is more appropriate, self-report or observational, and why? Would an index work well for any of the constructs? If yes, indicate it (them) and explain the reason. Can any of your variable be a scale? If yes, indicate it (them) and explain the reason. Would you be concerned about validity of the measurement? How? (How would you assess the validity?)
