Question
A researcher uses an experimental design to study the effect of music on memory. In this experiment, the Independent Variable is:a. musicb. memoryc. both music and memoryd. neither music nor memory
Solution
In an experimental design, the independent variable is the factor that the researcher manipulates to see if it has any effect on the dependent variable. The dependent variable is what the researcher measures to see if it changes as a result of the manipulations of the independent variable.
In this experiment, the researcher is studying the effect of music on memory. Therefore, the independent variable that the researcher is manipulating is music. The dependent variable, which is being measured for any changes, is memory.
So, the answer is: a. music
