A researcher is interested in testing whether students make healthier food choices after using a redesigned lunch tray, as compared to a standard lunch tray. What type of design would be most appropriate? a. between whjects
b. repewned measures
c. experimental
d. Quasi-experimental

Experimental

Explanation:

Experimental research is carried out in a scientific approach using two sets of variables.

The first variable acts as a constant used in measuring the differences of the second set.

The students are constant and the two different launch tray are the variables been measured. Data are generated from the experiment that is needed for the research.

Experimental method helps in generating data that are vital in making our conclusion and decision.

The researcher determines appropriate method needed in collecting the data and appropriate tool for analyzing the result.
