For these questions, you are given brief summaries of research scenarios and specific hypotheses. You need to choose which statistical test is appropriate to analyze the hypothesis given the context of the research scenario. Each scenario is worth 5 marks. 1 mark is for correctly identifying the appropriate statistical test. An additional 4 marks are awarded for justifying your answer with respect to

1. The type of data collected by researchers (i.e., continuous, ordinal, or nominal)

2. Whether researchers are investigating an association/relationship between at least two variables or are instead investigating differences between conditions using the same variable

3. If applicable, the number of conditions and/or factors

4. If applicable, the independence/dependence of observations between conditions

You may format your answers as either short paragraphs or bullet lists.

An educational psychologist was curious whether students who consistently sit in the front row of lectures achieved higher grades than students who consistently sit in the back row. He published an online survey available to university students in which participants self-reported which row they sat in during lectures throughout the semester and the their final grade point average at the end of the semester. He was interested in comparing the grade point averages of two groups of students: those who sat in front of the class and those who sat in the back. What analysis should he perform?
