Introduction

## Introduction

For this assessment I had to do a lab report on the data that I collected. I tested students on a wide range of physical aspects including Blood pressure, heart rate, sit and reach, height and weight etc.

I tested the student in the sports hall using different equipment, which included heart rate monitors, tape measures and scales etc.

When testing the student’s heart rate I tested them whilst they were standing, seating and lying down to get different readings. Also when doing the grip strength exercise I tested them on both arms left and right, I did this to see if people do have a stronger hand. I also tested both males and females to see if there is a difference in the results between the different sexes.

I tested 21 students so I could get a wide range of data so that I could analyse the data in greater depth. The more data you can collect the more accurate your results will be, because you can take the results from a wide range of people.  You get a more realistic average if there are more people because you’re not just seeing the results of two people.

I’m going to base my results on the difference between males and females.

I’m going to concentrate my results on the difference between males and females height, weight and heart rate.

## Hypotheses

Middle

59

60

61

54

56

Mean average= 54 Beeps per minute when the average male student is lying down.

Females resting heart rate

 88 52 68 60 76 61 59 68 65 67 62

Mean average= 66 Beeps per minute when the average female student is lying down.

You can see from the graph that the male & females resting heart rate has a positive coloration this is when the graph point are moving up and to the right. This means that there is a close coloration between males & females resting heart rate.

You can see from the results below that the females mean average is lot more than the male average. I used the mean average because it’s the most realistic average to use as it takes into account the very highs and the very low points and gives you an average reading.

### Weight

 77.8 75 74 63 69 71 69 88 70 75 73

## Male

Mean weight= 73kg is the average weight for a male student that was tested.

 52.9 61 50 60.5 60.7 60 59 58 61 54 56

## Female

Mean weight= 57kg is the average weight for a female student that was tested.

Conclusion

I think that males are heavier because they are bigger both taller and wider then females plus they have more muscle than females that’s why males are stronger. Muscle can be up to three times heavier than fat (Ian Turner GB head coach swimming- personal quote- 2001). Again this is why I would expect the males average to be a lot greater than it was.

In my hypotheses I suggested that I thought males would be taller than females. I suggested this because males tend to have a bigger frame.

From the results you can see that males were a lot bigger than the females. On average males were 14 cm taller the females. This is a big margin between males and females, as the females would have stopped growing now. “Some males don’t stop growing till they are 21 years old. (Microsoft Body Parts- CD-ROM 2000) So that means that some of the males might not of peak to they tallest just yet.

Through these diagrams, I will be able to find the median and the interquartile range. This will allow me to draw box-and-whisker diagrams, which will allow me to make further comparisons between girls and boys. I will also predict percentages of students who have a height or weight within a given range.
