The independent variable is the variable that is being manipulated by the researcher to see if it has an effect on the dependent variable (the outcome being measured). In this case, the independent variable is the method of instruction, specifically comparing computer-aided learning to a usual lecture format. This is the variable that is being changed in order to see if it has an impact on standardized test scores. The other answer choices (individual students, previous grades, interest in psychology) are all variables that may be measured or controlled for in the study, but they are not the variable being manipulated.
