Description

Students in an introductory statistics class (MS212 taught by Professor John Eccleston and Dr Richard Wilson at The University of Queensland) participated in a simple experiment. The students took their own pulse rate. They were then asked to flip a coin. If the coin came up heads, they were to run in place for one minute. Otherwise they sat for one minute. Then everyone took their pulse again. The pulse rates and other physiological and lifestyle data are given in the data.

Five class groups between 1993 and 1998 participated in the experiment. The lecturer, Richard Wilson, was concerned that some students would choose the less strenuous option of sitting rather than running even if their coin came up heads, so in the years 1995-1998 a different method of random assignment was used. In these years, data forms were handed out to the class before the experiment. The forms were pre-assigned to either running or non-running and there were an equal number of each. In 1995 and 1998 not all of the forms were returned so the numbers running and sitting was still not entirely controlled.


Variable Description

Alcohol: Regular drinker? (1 = yes, 2 = no)

Exercise: Frequency of exercise (1 = high, 2 = moderate, 3 = low)

Ran: Whether the student ran or sat between the first and second pulse measurements (1 = ran, 2 = sat)

Pulse1: First pulse measurement (rate per minute)

Pulse2: Second pulse measurement (rate per minute)

Year: Year of class (93 - 98)


Research Questions:


1.What is the relationship between Pulse 1 and Pulse 2?

2.Does pulse 2 depend on the weight of the participants? Is there a strong linear correlation?

Please include histograms and conclusions.

Please Provide me with your email address so I can email you the data, as it looks like I can not attach it here.

Thank you.
