The heart is the most important pump muscle in our body that pumps blood , thereby maintaining the flow of blood through the entire circulatory system. The pulse rate is the number of times it beats per minute. It can be determined by feeling pulse areas on body and by special BMP machines. An adult's normal resting heart rate (RHR) falls between 60 and 90 beats per minute. An athlete who is in great shape may have a RHR between 40 and 60. There is often shown a correlation between the weight of a person and pulse rate as athletes have a lower pulse rate than ordinary people. If you weigh more than your body frame can comfortably support, your heart works harder to provide the energy you require to function. The weight is therefore a factor that can affect the pulse rate.
The purpose of this report is to investigate the relationship between the weight of a person both female and male (kg) and the pulse rate. The purpose is to show how dependant the pulse rate is on the weight (kg). It is expected that the pulse rate will depend on the weight of the person. It is anticipated that person with a heavier weight will have a higher pulse rate than a person with a low weight.
[...] Both the female and males have a fairly big SD, which indicates the correlation is not too significant. In conclusion, the relationship of absolute body weight to changes of pulse rate is seen. The weight has an effect on the pulse rate. Students, both males and females, with a heavier weight tend to have a higher pulse rate. This investigation does not prove this entirely as there can be other factors, as the body fat percentage or muscle mass affecting the pulse rate.

[...] This will prevent the pulse rate from getting affected by physical movement and therefore give a more steady pulse rate answer. Conclusion: The weight of a person has an affect on the pulse rate, as this can be seen on the graphs for both females and males. The graph lines have same patterns with same swings. The male graph shows a bigger correlation between pulse rate and weight. Based on the t test we can also conclude the spread and relationship between the two variables. [...]
[...] Research question: How much does the weight of a person affect the pulse rate? Dependant variable: Pulse rate (BPM) Independent variable: weight Controlled variables: sitting position (calm), same age group, same amount of clothes, same procedures (no shoes). Materials: Weighing machine (measuring in kg) Pulse rate machine Method: 60 students (males and females) were collected of an age group from 16 to 19. All students were weighed without shoes with separate data sheets for males and females. Same weighing machines were used for all measurements. [...]
[...] The Standard deviation is the frequently used measure of the variability (spread) in a set of data. Here the spread is higher for the weight with 5.985 than for the pulse rate with Roughly 68% of normally distributed data of the variants lie within standard deviation. The lower the SD the closer it is to the mean. Here the SD indicated that it tends not to be very close to the mean. The SEM is a technique for testing and estimating causal relations. It shows the relationships between variables in the data set. [...]
[...] Meaning that people with a bigger weight tend to have a higher pulse rate. The places the pulse rate increases, the weight line also goes up. There are places the graph lines overlap each other and do not fit accordingly to each other. Females (age: 16-19): Analysis: On this graph 41 females are plotted. There is a correlation between the pulse rate and weight. The lines fluctuate very alike though there is a big difference between some of them, and there are not outliers in the raw data. [...]
