Expectations 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.
Question 3
A sociologist wanted to investigate how well a person's salary can be predicted by the combination of their intelligence quotient (IQ) and the number of years they have been formally educated. She therefore published a survey in which participants self-reported their salary in dollars, completed an IQ battery, and self-reported the number of years they have spent in post-secondary education. The IQ questionnaire was collapsed into a continuous-valued composite IQ index. What analysis should the researcher perform to assess the combined influence of IQ and educational attainment on salary?
