Description of your data set Please assume that this data file presents measurements from a random sample of 280 Australian university students. (But please remember that this is a completely artificial data file. It does not reflect any real world measurements or associations.) Within R Commander the data set is called 'pa' which is short for physical activity. There are 280 lines of data. The variables are: sex – Gender of respondent (male or female) age – Age in years of respondent BMI – Body Mass Index of the respondent coded as 'underweight', 'normal', 'overweight' and 'obese' overweight – BMI of respondent recoded as either 'overweight' or 'not'. 'overweight' includes everyone from the overweight and obese categories in the BMI variable and 'not' includes everybody who was underweight or normal on the BMI variable. MVPA – the respondent's self-reported minutes of moderate to vigorous physical activity per week. logMVPA – logarithm transformed MVPA (the logarithm transformation is used to produce a variable containing the same information as MVPA but with a more symmetric distribution). GPA – the respondent's university grade point average. Results a from each study Unit are scored as Withdrawn Fail=1, Fail=2, Conceded pass=3, Pass=4, Credit=5 , Distinction=6 and High Distinction=7. The GPA is the score averaged across all Units which the student has completed. yourID – your student number. If this is not your student number you are looking at the wrong data file!
