David Harper, the marketing manager of a large cosmetic company, observes that when the company decreases the price of its premi
um deodorant brand, there is an increase in the level of sales of the brand. If the company increases the price of its premium brand, there is a decrease in the level of sales of the brand. In the context of experimental research studies, the changes in price represent the:a. independent variable.b. dependent variable.c. placebo.d. confederate.
Independent variable is one that represents a variable that influences or affects another variable. Independent variables are the determining factor, condition, or cause for a given outcome, effect, or consequence. They are also the factor manipulated by the researcher in order to determine the factor's relationship with the observed phenomenon, to see what influence it has on a possible outcome. For this reason, we can say that the example of the independent variable that is presented in the question is price changes.
