Compare and contrast weak and strong experimental designs.
What will be an ideal response?
Ans: Weak experimental designs are designs which do not control for confounding extraneous variables and thus are not able to isolate the effect of the independent variable. Strong experimental designs are those that control for confounding extraneous variables and have high internal validity. In strong experimental designs, typically there is at least one technique to control the confounding extraneous variable as well as have a control group who does not receive the experimental treatment. Thus, when the experimental and control groups are compared on the dependent variable, the differences between can be attributed to the manipulation of the independent variable.
