Experimental Designs
Pages 20-22 and Chapter 10.
An experimental research design uses quantitative procedures to determine whether an activity or materials (an intervention) make a difference for participants. Two groups are formed: a control group and an experimental group. The experimental group receives the intervention and the control group does not. The performance of each group is assessed by measuring key variables and the measurements are compared statistically to see if the intervention made a difference.
