Analysis Report

You need to prepare a group analysis report (using Microsoft Word), which requires an amount of computer work and written comment. You may need to seek guidance from your lecturer in the class. Do not leave things until too late!! Each task describes what you are required to do, so please follow these carefully!

In this report, you will analyse a randomised subset of a student survey. It is an in-class survey of statistics students over several years. We only consider the First Year data. This subset only has three variables, namely Sex [F and M denote female and male student respectively], Smoke [Smoker? No or Yes] and GPA [College grade point average].

Task 1: Identify data type
Identify each variable (i.e., Sex, Smoke and GPA) in the subset whether it is categorical nominal, categorical ordinal, quantitative discrete or quantitative continuous.

Task 2: Show the difference of GPA by Sex
Construct side-by-side boxplots for the GPA variable by the Sex variable (i.e., the two groups are female students and male students).
Calculate the Q1, Q2, Q3, interquartile range and whisker limits for the GPA variable of the female and male groups separately.
Use the respective median and inter-quartile range to compare the data position and variability or spread of GPA for the female and male groups separately.

Task 3: Calculate the percentage of smoker by Sex
Create a contingency table to show student's Sex frequencies by the Smoke variable (i.e., a smoker or not).
Calculate and compare the percentage of smoker in the female students and the male students separately.

Conclusion:
From the Task 2, you should have some idea of the difference of the distribution of GPA for the female students and male students. Also, the result from Task 3 would indicate which group has a higher smoker percentage. Write a short report summarising your main findings.
