Breathing Rate Experiement Essay, Research Paper
??????????? The people
doing the breathing rate experiments are doing the experiment to see how fit
each person is. They do this by timing how long it takes for their breathing
rate to get back to their normal rate (the rate it was at before they started
to do the exercise). The method they stated they would use is extremely vague
and is not very concise. The experiment was to find the ?effect?. The
experiment could have been improved if they had a specific effect that they
were going to measure. An example of this would be to find out if boys were
better than girls at jogging for 5 minutes. ??????????? There are
also many things that are not fair about the test. Firstly, there is one male
and two females. This means that if they were testing to see whether or not
boys were fitter than girls they could get biased results. This would result
because the two females they chose could be extremely fit and the male could be
extremely unfit. To overcome this problem I would use an equal amount of males
and females (5 males and 5 females). I would also make sure that each of the
people being tested would have a uniform lifestyle. Although I could never be
completely sure if they had the exact same lifestyle I would try to find the
closest match. They also do not state which form of exercise they are doing and
this means that one person could have been running at 5 miles per hour whilst
another could have been cycling at 2 miles per hour. This meant that their
method was not very suitable at all. I would change this by making them do a
uniform exercise like jogging at 5mph. Other factors which made their method
unsuitable were the way in which they measured the results. It looks as if they
have asked each person to measure their own amount of breaths they have taken. I
have come to this conclusion because Johns result seems to be anomalous. This was
probably because he had measured his own result and had probably measured his
exhaling separately from his inhaling. This would cause his results to double.
A way to overcome this problem would be to use a heart rate monitor and a
breath meter (respirator). This would guarantee that the results were accurate.
I would also take an average by repeating the test at least 4 times. This would
help me because one result may come out with odd results and this would be a
way of making that result less affective. It would also ensure they were much
more accurate. ??????????? To extend
the investigation I could do another experiment using people with worse
lifestyles. I could then compare these results with the ones I had obtained in
the previous test to see how peoples lifestyles affects their breathing rate. I
could also use more people as the more results I obtain the more accurate the
results will be.???????????
