Question
The problem
A student survey was conducted at a major university. Data were collected from a random sample of 236 undergraduate students, and the information that was collected included physical characteristics (such as height and handedness), study habits, academic performance and attitudes, and social behaviors. In this exercise we will focus on exploring relationships between some of those variables. Note that (a) these are real data, and (b) the symbol * in the data set means that this observation is not available (this is known as a 'missing value').

Height Self-reported height (in inches)
Cheat Would you tell the instructor if you saw somebody cheating on an exam? (0=No, 1=Yes)

Gender Relevant - categorical Alcohol Relevant - quantitative Height Not relevant- quantitative Cheat Relevant - quantitativeExplanation / Answer
Gender - Relevant qualitative
Alcohol - Non-relevant quantitative [Because some students may lie for privacy]
Height - Non-relevant quantitative [Because maybe he/she is not correct]
Cheat - Non-relevant qualitative [Because maybe he/she want to show a good impression to the investigator so most of the students will say yes]
