A research team collects data from two groups, in one group, they administered a learning task that provided feedback (i.e., telling the participant if they were right or wrong) and in the other, the participants were not provided with feedback. The research team is interested in the number of trials the participants spent learning as a function of their independent variable. Below are the number of trials each participant spent. Use it to answer the following questions.
