Design an experiment must design an experiment that will test your hypothesis. Plan for collecting the sample response variable: Research design should specify the time so that every activity can be completed in time and the researcher can produce a research report in time. True experimental design true experimental research designs are those where researchers have complete control over the extraneous variables & can predict confidently that the observed effect on the dependable variable is only due to the manipulation of the independent variable.

True experimental design true experimental research designs are those where researchers have complete control over the extraneous variables & can predict confidently that the observed effect on the dependable variable is only due to the manipulation of the independent variable. Formal experimental designs offer relatively more control and use precise statistical procedures for analysis. The cause must precede the effect.
