Other findings the data showed include:
That the greater the mass of an animal the higher basal metabolic rate the animal has. Larger animals expend more total energy.
Based on the results from the data analysis the general trend line is showing a positive slope. The trendline shows that the higher the body mass the higher the basic metabolic rate. However, there were several animals of the same general body mass that had vastly different BMR’s falling either way above or below the general trendline. Even with the outliers present the general trend of mammals shows that the higher the body mass the higher the basal metabolic rate. The average body mass for a mammals was 11,185.45g with a standard deviation of 36,113.83g and a BMR of 10.12, with a standard deviation of 25.89. The relationship from this data set supports my hypothesis.
Based on the results of the data analysis the general trend line shows a positive slope. This general trend shows that the higher the body mass in birds the higher the metabolic rate. The relationship in this data set supports my hypothesis. The average body mass of a bird in the data set is 305.30g with a standard deviation of 480.56g and the average basal metabolic rate is 1.30, with a standard deviation of 1.56.
That birds have a higher overall mass-specific basal metabolic rate compared to mammals.
The average mass-specific BMR for birds and mammals is not equal to one another. The average mass-specific BMR for birds is 0.011 and the average mass-specific BMR for mammals is 0.0051. On average a bird’s mass-specific BMR is twice as fast as a mammal.
That birds have a lower average mass than mammals.
The data set supports my hypothesis. From the data the average body mass of a bird is 305.30g whereas the average body mass for a mammal is 11,185.24 grams. The average mass of a mammal is greater than the average body mass of a bird.
