Is the height of adult males ages 18-30 related to wingspan?
3
Height vs. Wingspan Our first quantitative variable is wingspan measured in inches, of adult males between years of age. Our second quantitative variable is height measured in inches, of adult males between years of age. Data was gathered by randomly selecting adult males in this age range and measuring them
4
In order to discover if there was a significant correlation between height and wingspan, we gathered information from 25 men between ages of to participate in the study. Age in Years Wingspan (In) Height (In) Wingspan-Height proportion 18 65.2 65.1 1.002 22 72.2 70.6 1.023 25 68 69.2 0.983 27 69.3 68.9 1.006 19 65.9 63.9 1.031 23 67.5 0.976 26 72.1 69.9 68.7 66.1 1.039 29 70 72.3 0.968 30 76 75.1 1.012 20 67.3 1.000 21 74.7 1.058 67.8 0.993 Age in Years Wingspan (In) Height (In) Wingspan-Height proportion 22 68.6 1.000 26 80.3 76.1 1.055 28 69.2 69.1 1.001 19 67.9 66.7 1.018 68.3 0.994 27 72.3 69.4 1.042 30 66.3 65.9 1.006 25 71.4 70.3 1.016 24 71.2 1.003 23 70.6 68.9 1.025 20 72.8 68.4 1.064 70.9 70.5

Here is a side by side comparison of each individual’s height and wingspan in inches.

Results and Summary Linear correlation coefficient r=0.8705, there is a moderate to strong positive linear relationship. Y=0.88x+20.88 Critical Value=.396 We had 25 individuals in the sample, which equals 23(df). With significance level of .05, the absolute value of the correlation coefficient is This value is above .381, so there is only a statistically significant relationship between wingspan and height, and the hypothesis must be rejected unless more subjects are included in the study.
11
Conclusion The relationship between wingspan and height is only statistically significant. 72% of individuals measured had wingspans greater than that of their height, 8% had height and wingspan that were the same, 20% were taller than wingspan. The average proportion difference between height and wingspan is Our conclusion is that wingspan and height are related and wingspan is usually about 1 inch greater than height in adult males.
