I am having difficulty with a homework question relating to a dataset with 92 cases. I have not been able to paste the table here but have included the variables (see below):
Pulse Before Pulse After Ran? Smokes? Gender Height Weight Activity Level
This data came from an in-class activity in a college introductory statistics class. Some general data was collected for each student, and then each student was asked to flip a coin. Those whose coin came up heads were asked to run in place for a minute or so. All students measured their own pulse rate both before and after the running activity took place. Note that the two measurements were made on those who ran and on those who did not.
In addition to the pulse rate before and after the running took place, the data recorded whether each student ran or not, whether they smoked, their sex, height (in inches), weight (in pounds) and activity level. This last is coded
The question I am having difficulty understanding is:
Make a single display of all the weights. Choose a display that shows the shape of this distribution. Try more than one scale. Then comment on the shape you see and anything else you find. (You do not need to submit the actual graph.) If anyone could explain what is required here in simple language, this would be most appreciated. I am having difficulty understanding:
(1) what is supposed to be included in the graph (e.g. which variables)
(2) what kind of graph is necessary.
Bear in mind that the graph would be based on 92 cases.
Thanks in advance.
