Question

Here is a short essay about an investigation. Does jogging keep you healthy? Two independent researchers interested in whether exercise prevents colds interviewed 20 volunteers about the frequency with which they caught colds. The volunteers, none of whom exercised regularly, were then divided into two groups of 10, and one group participated in a six-month regimen of jogging three miles every other day. At the end of the six months, the frequency of colds among the joggers was compared, both with that of the nonjoggers and with that of the joggers prior to the experiment. It was found that, compared with the nonjoggers, the joggers had 25% fewer colds. The record of colds among the joggers also declined in comparison with their own record prior to the exercise program. Here are also four questions/tasks. Write a paragraph to answer each one of them: (1) Identify the causal hypothesis at issue. (2) Identify what kind of investigation it is. (3) There are control and experimental groups. State the difference in effect (or cause) between the control and experimental groups. (4) State the conclusion that you think is warranted by the report

Explanation / Answer

The causal hypothesis in question is jogging prevents/reduces cold. This is an experiment, where different treatments were imposed on factors and their response is recorded as dependable variable. The control group i sthe baseline treatment group, which is default treatment. The response is noted to find a basis for comparison among expeerimental groups and the control. The study is descriptive one with no statistical significance, sso conclusion might not be generalized one.
