1. are experimental designs more reliable than observational study ? 2. does experimental designs gives more accurate resutls than observational study ?
Why is random assignment used in between-subjects experimental designs? a. To increase the variance within the groups. b. To eliminate systematic differences between the groups. c. To manipulate the independent variable. d. To avoid volunteerism.
Classical experimental designs involve: Control and experimental groups Independent and dependent variables Pre-tests and post-tests All the above
Factorial designs a) Are generally not appropriate for experimental research b) Measures a single independent variable in depth c) Require an increase in sample size if a pretest is used d) Allow for generalization across variables with an interaction effect is present
