What are the hallmarks of true experimental approaches? Give three, and demonstrate each with an example.
What will be an ideal response?
Ans: In order to discuss the hallmarks of a true experiment, one must first define a pure experiment: it occurs when the researcher manipulates the independent variables. Participants are randomly assigned to conditions. There is an attempt to control extraneous variables and measure as many third variables as necessary. In class, we conduct a taste test. Students count off 1–2 to be placed in either a feedback or no feedback group (they are told the correct answers as we go along or not). Further, let us say students choose to taste the difference between different brands of doughnuts. To determine which doughnut sample comes in what order, we write down all possible orders on pieces of paper and shuffled the papers. A slip of paper is drawn to determine each trial. So, students are placed in groups randomly and receive the conditions of doughnuts randomly. Next, there is an attempt to control extraneous variables by blindfolding participants so they cannot see what they are eating in case appearance matters. Finally, we consider third variables such as age, gender, and whether or not an individual ate lunch before they came into class to measure third variables. So, our taste test is a true experiment.
