In a research studying the effect of sugar intake on concentration, the researcher randomly assigns student participants to either a group that receives water before taking a test or juice and candy before taking a test. The dependent variable in the study is the:
A)sugar consumption
B) water
C)test scores
D)control group
E)the time of day
My answer was sugar consumption but it was marked wrong. Any help?
A dependent variable is essential in the experimental process. By definition, a dependent variable is a trait in the experiment that is manipulated since it mainly depends on the independent variable. Therefore, the dependent variable in the experiment would be the sugar consumption.
