- Please give an example of Validity experimental study.Which term is used to best describe the experimental treatment that is initiated/manipulated by the researchers? a)independent variable b)dependent variable c)outcome variable d) extraneous variableThe following are reasons why randomized control trials (RCTs) are not used to investigate all research questions, except: a. RCTs can be expensive, which can make it difficult if funding is limited b. RCTs can be time-consuming, and it may take months and sometimes years to obtain final results c. For certain research questions and/or certain types of exposure variables, it may not be ethical to conduct an RCT d. RCTs are less valid than observational analytical study designs
