Range Rule of Thumb for Interpreting s The 20 brain volumes $(c{m}^{3})$ from Data Set 8 “IQ and Brain Size” in Appendix B have a mean of $1126.0\text{}c{m}^{3}$ and a standard deviation of $124.9\text{}c{m}^{3}$ . Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of $1440\text{}c{m}^{3}$ be significantly high?

Step 1

Using the following range as a guide, find the values that are noticeably low or high:

Values that are noticeably low are indicated by $\mu -2\sigma $. The values lower than or equal to this $\mu -2\sigma $ values are regarded as being extremely low.

Values that are unusually high are indicated by $\mu +2\sigma $. The values higher than or equal to this $\mu +2\sigma $ value are considered to be significantly high.

Step 2

Here, the values that are noticeably low and high are determined as follows:

$\text{Signinficantly low}=1.125-2(124.9)=875.2$

$\text{Signinficantly high}=1.125+2(124.9)=1374.8$

Step 3

Consequently, the indicated brain volume value with $1,440c{m}^{3}$ is significantly high because it is greater than $1,374.8c{m}^{3}$.
