Abstract: use past tense- very specific details about the experiment.
A: purpose- entire class- athlete vs. non-athlete, to see the different between athlete and non-athlete in
the heart rate.
B: Method- be brief, Rest and Exercise heart rate
Results: statistical results, ST. Dev, 95% confidence interval, and T-test
C: Conclusion- did athlete have lower heart rate than non-athlete.
Introduction: Start with journal article background that is relevant to what we did. Like heart rate at
rest, heart rate after exercise, or college athletes and non-athletes young.
Why it is important to study this? You can say to know if being athlete will protect your life from fast
beating heart, and can protect you from disease or no.
Purpose: to see the different between athlete and non-athlete in the heart rate.
Hypothesis: I think being athlete will reduce the number of beating heart for the athlete, and keep them
more save from disease.
Material and method:
19 students were in the school, some of them were athlete, and other was not. The students were in the
class when they did the experiment. The age of the students was between 20 to 33. They took the heart
rate when they were resting, and they took it again after exercise.
Procedure: all the students were sitting, and resting, and the professor had the timer. Students got read by putting their fingurs under their ear to count the beating of the heart rate, and the professor
was ready to set the timer for 1 minute. So, they count the beating heart at the first time until the
professor told them to stop(when 1 minute is pass) and they also measure it 2 more time, and each time
were per minute. After that, they took the average for the three time that they measured and recorded
it. The other way of measure the heart rate was after exercise. So all the students stand up and jump up
and down for only 1 minute, and then they measure the beating of the heart rate 3 times, each time per
minute, and the took the average for the three time for each students.
Results:
In this section, you just have to describe the histogram, and the paragraphs and put all of them here in
the result section. No opinion and no sources in this part. Just talk about the datat that we had from our
experiment.

I want to explain to you, the t- test for all students who are athlete or non-athlete for the resting and
after exercise is 3.52E-10. So the value is not significant because P>0.05. for the mean change there is no
t- test. For the athlete and non-athlete students when resting, the t-test=0.39 which is also > 0.05 there
is no significant different. For the athlete and non-athlete students heart rate after exercise, the t-test =
0.79 which also > 0.05 and that means there is no significant different between athlete and non-athlete
regarding to these data. So you can mention in the discussion section that there is no significant
different between athlete and non-athlete regarding to the date that were taken from the students, but
in the other experiments from the sources there is significant different between athlete, and non-
athlete. The reason why the data show that there is no significant different between athlete and non-
athlete because some of the students who was not really athlete consider themselves as athlete
students or the opposite.
Just describe it, no using of sources or opinion.

Discussion:
Put the conclusion first, then explain why you came to this conclusion using your results, and you some
article to see the different between our experiments and the other, but try to talk about our
experiments and our data more. Mention the t- test the significant different. So you can mention in the
discussion section that there is no significant different between athlete and non-athlete regarding to the
date that were taken from the students, but in the other experiments from the sources there is
significant different between athlete, and non-athlete. The reason why the data show that there is no
significant different between athlete and non-athlete because some of the students who is not really
athlete consider themselves as athlete students or the opposite.
