Detailed explanation-1: -It is important to standardize experimental procedures to minimize extraneous variables, including experimenter expectancy effects. It is important to conduct one or more small-scale pilot tests of an experiment to be sure that the procedure works as planned.
Detailed explanation-2: -You can increase the validity of an experiment by controlling more variables, improving measurement technique, increasing randomization to reduce sample bias, blinding the experiment, and adding control or placebo groups.
Detailed explanation-3: -Experimental research is mainly used in science subjects such as physics, chemistry, medicine, biology etc. Experiment requires two variables, one independent variable, and the other dependent variable.
