Question

Several groups of researchers were conducting experiments to study how exercise affects cholesterol levels. One group had college students run two miles a day for six weeks. Another group had senior citizens participate in gentle water aerobics twice a week for a year. Cholesterol levels dropped slightly among the college students but dropped significantly among the senior citizens. Based on these results, what should the researchers plan to do next to validate the findings?

Answer 1

Answer:

Design more studies testing the effect of duration and intensity of exercise on cholesterol levels in different age groups.

Explanation:

Answer 2

Based on the result, the researcher will now see if the time duration of exercises will affect the cholesterol. So, now the time variables will be interchanged for the exercise.  

What is an experiment?

An experiment is a scientific procedure that makes a discovery based on the hypothesis and calculations and gave a fact or result. Experiments are done to prove the hypothesis.

Here, the experiment is to control cholesterol by exercise. Two variables are taken for experimentation, one is a senior citizen performing water aerobics and the second is college students performing running.

Thus, based on the findings, the researcher will now examine if the length of exercise sessions has an impact on cholesterol. Therefore, the exercise will now swap the time variables.
