Short Answer Scenario 2: Imagine you read a news headline that states: “Taking notes by hand may lead to better learning.” In the study, researchers had students take notes on a TED talk in a classroom and then tested their understanding of the material with a multiple-choice exam. A third of the students were randomly assigned to take notes with a laptop, another third was randomly assigned to take notes with an iPad, and the last third was randomly assigned to take notes by hand. The results suggested that there was a statistically significant difference in exam scores such that participants who took notes by hand performed significantly better than the participants who took notes by laptop or iPad. What is the independent variable? How many levels are there of the independent variable? What are the levels of the independent variable? What is the dependent variable? What type of study do you need to make this claim? Correlational study or experiment?
