Question

A savvy group of graduate students are developing a new corporation, GraduateSchoolOrBust. Their mission is to promote success in graduate students’ academic outcomes. In developing their initial study, they seek to measure success as graduate or not graduate from school. They will plan to examine the effects of confidence (as measured by the tool Rate Your Confidence Scale), GRE score, and test scores from Biostatistics. They will follow one large group of graduate students from admission to graduation.

Identify the study design, the independent and dependent variable(s), covariate (if appropriate), and appropriate statistical test for data analysis.

Answer 1

The study design is observational study design.

The independent variables are confidence, GRE test score, and test scores from Biostatistics.

A possible covariate is confidence.

The appropriate statistical method as per the objective of the students is logistic regression using which they can make a predictive model to check whether the student graduated or not.

Note: We do not generally call logistic regression a statistical test but testing is a part of it. There is no statistical testing procedure which can be used in the given situation, maybe your professor is considering it a test as other people do.

Good luck with your studies!!!
