SUMMARY

The discussion centers on determining whether to use a one-sample or two-sample t-procedure to analyze absenteeism data between on-campus and off-campus students. The consensus indicates that a two-sample t-procedure is appropriate, as it allows for the comparison of means between the two independent groups. The suggestion to pair students based on characteristics like GPA and course load is not applicable due to the lack of such data in the study. Therefore, the two-sample t-procedure is the definitive method for this analysis.

PREREQUISITES
  • Understanding of two-sample t-procedure
  • Knowledge of statistical sampling methods
  • Familiarity with hypothesis testing
  • Basic concepts of absenteeism measurement
NEXT STEPS
  • Study the application of the two-sample t-procedure in real-world scenarios
  • Learn about assumptions underlying t-tests, including normality and equal variances
  • Explore statistical software options for conducting t-tests, such as R or SPSS
  • Investigate the impact of sample size on the power of t-tests
USEFUL FOR

This discussion is beneficial for statisticians, researchers in educational settings, and students learning about hypothesis testing and statistical analysis methods.

Homework Statement



A university is interested in whether there's a difference between students who live on campus and students who live off campus with respect to absenteeism. Over one semester, researchers take random samples of on-campus and off- campus students and record the number of classes each student misses. State whether you'd use one-sample or two-sample procedures to analyze the data.

The Attempt at a Solution

I feel like either could work. On the one hand, you could just calculate the statistics for each group, off-campus and on-campus, and conduct a two sample t-procedure with that data. While on the other hand, you could pair one person with one from the other group based on similar characteristics such as GPA, course load, and extracurricular activities. I'm not sure which would be correct.

The problem stated what data the researchers recorded. It wasn't given that they recorded information about GPA, course load etc.
