18. Advantages Most powerful design. Decreases the effects of extraneous variables Conditions can be created. Greater degree of purity in observation. Disadvantages Ethical problems. May harm to human In some setting hard to control extraneous variable Some times impractical. Lengthy process. difficult to get cooperation participant. True experimental design 8/6/2019 18 Ms.Dhara Vyas, Assistant Professor, DPCN

19. Quasiexperimental research design Manipulation of independent variable, but absence of either randomization or control group. 8/6/2019 19 Ms.Dhara Vyas, Assistant Professor, DPCN
