Nt1310 Unit 3 Case Study

b) From the data provided, the greatest variance is in the Height data collected, it was the most variable and most scattered
In addition to the large variance, it also had the greatest interquartile range, meaning that there was a large range or quantity of data between the first and third quartile
Moreover, height had the largest standard deviation, making the spread of the data quite wide and somewhat more scattered compared to the other two sets of data
In contrast, right cubit length had the smallest variance, making the data less spread out, less scattered compared to the heights of people
Also, right cubit length had the smalls standard deviation making the spread of the data less spread
The variance of wingspan is quite large compared to the variance of right cubit length. In context of the data provided, for such a small sample size, this is quite a large variance. This means that there is a great amount of variability in people's wingspans. It is very different and very large compared to the variance of right cubit length.
Moreover, wingspan also a notable standard deviation, though not as large as the standard deviation of the height, it symbolizes the sizeable difference of people's wingspans in the data collected. Though, it is larger than the standard deviation of right cubic length, in terms of what is being measured, it is acceptable.
Wingspan also has a larger IQR compared to the right cubit length data. The large numbers involved in this study like, 66.3 cm will create more variance and a greater range compared to data collected about right cubit
