Research question
Is there a correlation between the leg length, height and stride length?
Apparatus
1. Measuring tape
2. Paper
3. Pen
4. Calculator
Procedure
1. Using the measuring tape; measure the leg length by putting the starting end of the tape on the malleolus, and the ending point on the iliac crest. Make sure the person you are doing the measurements on does not feel uncomfortable.
2. Record the length of the leg and height in two different columns.
3. Ask the person to walk five metres and count the amount of steps he/she takes.
4. Write down the amount of steps the person took.
5. Divide five metres with the amount of steps taken in order to find the walking stride length.
6. Plot two different graphs on Excel; one that compares the leg length to height, and another one that compares stride length and leg length. Make sure to refer to the r^2 value when stating whether a correlation exists.
Conclusion
From Graph α, which compares the leg length to height, it can be seen that there is a strong positive relationship. As the individual's leg length increases, so does the height. The R^2 value is circa 0,92 which is close to 1, and ergo, the data is more accurate in predicting a relationship between the two sets of data. This means that as the leg length of an individual increases, so does the height. This relationship could be explained by the structure of the human body, as the length of the leg increases, the rest of the body would also need to be longer in order to maintain a symmetry and normal proportions of the body. Therefore, the height of a person would be reciprocal to the length of the leg of an individual.

... end result of stride length that one would calculate at the end of the experiment. To improve this, one could possibly paint the bottom of the individual's feet. This would allow oneself to actually have a very reliable record of the stride length, and not solely based on counting strides. This would allow us to measure the stride length and not purely divide a certain distance (in this experiment 5 meters) by the number of strides that a person counted to have taken.
Furthermore, one could also compare the effect that the three different age groups have on the average human's stride length. One could conduct the experiment on humans with the three different age groups, teenagers, middle aged individuals and an elderly group of individuals. One could see the impact that age might have on the data that one would collect regarding their stride length and leg length.
1.There will be two groups, the control and experimental groups. Each group will have the same amount of participants with equal numbers of boys and girls. The first group will be the control group(rest). The second group will be the experimental group(exercise).
When measuring the entrance lines to the two parks we collected data on people in groups of five. When measuring in terms of time we started the clock when the first person began the entrance process and stopped it when the fifth person in that same line made it through the gate. We made note of the group’s total time and the amount of males, females, and children (measured by the same criteria as above). We chose to record entrance times in terms of five person groups ...
The step test was conducted in the lab room. The first participant measured her pulse rate for 30 seconds before starting the exercise. Her pulse rate was calculated to determine the number of beats per minute. She then stepped on the platform (up and down) and continued at a...
This experiment was completed in order to compare calf circumference as well as weight to jump height. If a person has larger calves then they will likely be capable of reaching a higher vertical height. It can also be shown that since males tend to have larger calves, they can jump higher. A larger calf circumference is more likely to reflect a high vertical jump due to the fact that the fat content of the calves in the experiment was accounted for, therefore a large calf measurement in this experiment means a muscular calf. It is common knowledge that more muscle will result in stronger legs leading to a higher vertical.

There was a series of people used in this experiment to look at blood pressure. The first step was to take the subjects normal blood pressure, then after showing them a scary clip retakes the blood pressure. While taking blood pressure consider age, weight, family history, commitment and gender to see if the subject has low or high blood pressure normally. After receiving all the data the charts that were made were based on age and gender.

Let’s go back to the study by Grilo and Pogue-Geile (1991). In this study, the correlation for height between twin pairs is 0.80. Even if we assume that 80% of height is determined by genes, there is a huge 20%. Let’s suppose that your genes determined your height as minimum 5 feet. With a healthy diet, exercising, staying away from smoking, drugs, and excessive consumption of alcohol, the remainder 20% of environment factors may enable you to height up to 6.4 feet.
* Age of the person exercising * level of fitness and recovery rate * gender of candidate * temperature * amount of recovery time KEY VARIABLE: - The variable that I will be using is the duration of exercise, this is because it is easy to measure against any candidate and get a correct accurate reading from it. If I chose the type of exercise I will get readings that might not be correct because some types of exercises are
the mean for leg length to torso length was 1.59 for humans and 1.13 for grasshoppers. In the graph the human column is higher than the grass hoper column as well because the grasshoppers have a smaller leg length compared to the body length and this is opposite to what I predicted in the hypothesis.
Many factors can influence the results of testing this hypothesis. All variables have been controlled except for the variable gender. Both the male and female subjects are close in age (< two years difference), both are nonsmokers, both possess small body builds for their respective gender, and both have no debilitating medical conditions (e.g., asthma, diabetes, heart condition). Controlling these factors allowed for the testing of the hypothesis, which is focused strictly on gender.
A simple formula may be used which gives a correlation to the 95th percentile of BP for the 50th percentile for height up to 16 years of age.[7]
From the graphs, it could be determined that the results are fairly precise due to the data points being fairly close rather than scattered. This can be seen as all the points are relatively close to the average value on graphs 1 and 2, not causing the trend line to be skewed.
In the past, people have always tried their own ways of using daily measurements. It was needed and used for daily trade as well as further businesses. These things could only have been made if the people knew they were being fair and honest; hence, the reason that different measurements needed to exist. Many short distance measurements were based on the lengths of the human body. The width of a thumb was used to resemble the inch, which we used today in the English System of Measurements. The foot, which is twelve inches, was compared to the length of the human foot; however, today it is derived to be longer than most people’s feet. The yard, which is equal to three feet, was inferred to be the length from the tip of the nose, to the end of the middle finger when the arm and hand are extended. The Anglo Saxons of England measured these short differences in their own ways too. The length of three barleycorns was their length of the inch (it was very close to the modern length). Then in 1066, the Normans conquered England and brought back to England the Roman tradition of the twelve inch foot. During the reign of Henry I the foot became official and was engraved on the base of a column of St. Peter’s church in London (Rowlett, R. (2001). A dictionary of units of measurement. English customary weights and measures). He also arranged the yard to be established in England as well. Although, inches, feet, yards etc. measured shorter distances, miles were used to measure much longer distances. This mile was a Roman unit, which was primarily the length of 1,000 paces of a Roman legion. The “pace” was meant to be two steps, about five feet, which measured the mile to be roughly about 5,000 feet.
