Does regular exercise reduce the risk of a heart attack? Here are
two ways to study this question.
Example Study 1: A researcher finds
2,000 men over 40 who exercise regularly and have not had heart attacks. She
matches each with a similar man who does not exercise regularly, and she
follows both groups for five years.
Example Study 2: Another researcher
finds 4,000 men over 40 who have not had heart attacks and are willing to
participate in a study. She assigns 2,000 of them into a regular program of
supervised exercise. The other 2,000 continued their usual habits. The
researcher follows both groups for five years.
Review the example studies above and answer the following
questions in your main post:
After reviewing the examples above, create your own study that
will determine if regular exercise reduces the risk of a heart attack.
Is your study more similar to example study one or example study
Given that example study one is an observational study and example
study two is an experiment, is your study an observational study or an
experimental study? Explain.
Why does the second way of studying the question (the experiment),
give more useful information about whether exercise reduces the risk of heart
What population do you think the researcher wants information
about in example study two? What was the sample in this case? Does your study
examine the same sample? Explain.
THIS IS NOT A PAPER I JUST NEED THE QUESTIONS ANSWERED IN PARAGRAPH FORM!!
