T. j. saw a commercial that claimed covering a cut with an adhesive bandage will the wound heal faster. he decides to design an experiment to test this claim. for his experiment, t. j. finds two friends with cuts on their hands. one friend covers her cut with an adhesive bandage, while the other leaves his cut uncovered. they make observations about each cut every morning until they both heal. if the wound that was covered with the adhesive bandage heals in less time than the one that was not covered, t. j. will conclude that using an adhesive bandage a wound heal faster. (a) identify three variables that were not specifically controlled in the experimental design. (b) for each of these variables, describe how they might have affected the outcome of t. j.’s experiment. (c) for each of the variables listed, suggest a way to better control them if the experiment were to be repeated.
