**Part
1-**Inferring
Height from Femur Length

**Analyzing
Your Results**

- How accurate were you in inferring height from femur
length? Explain.

**(Answers will vary but expect a variance of up to 5
cm) **
- Were factors such as gender and race taken into account
in this computation? Explain.

** (No. Only a single computation that did not include
gender or race differences was used in estimating height)
**
- How might the accuracy of this calculation be improved?

**(The calculation used was most likely developed for
white males. So although it can be used for other groups,
it may not be accurate across the range. In order to increase
the accuracy of individual measurements, one would need
to develop custom equations for each sex and race (as
seen later in the exercise.)) **

**Part
2-**Inferring
Height from Humerus Length

**Analyzing
Your Results**

- How accurate were you in inferring height from humerus
length? Explain.

** (Answers will vary but should have less of a variance
than observed in previous exploration) **
- Were factors such as gender and race taken into account
in this computation? Explain.

**( Only a subject's gender was taken into consideration
when estimating height) **
- How might the accuracy of this calculation be improved?

**(As with the previous exercise, one would need to develop
additional computations that include anatomical variance
based upon race) **

**Part
3-**Inferring
Height from Tibia Length

**Analyzing
Your Results**

- What was an advantage in using the tibia method for
determining height?

**(Variances for both gender and races were included
in the computation) **
- What were the disadvantages for using the tibia method
for determining height?

**(The tibia may be more difficult to measure. Data was
not given for the Mongoloid female computation. There
were only three racial categories from which to select.)
**
- Were factors such as gender and race taken into account
in this computation? Explain.

** (Yes - However, the races were limited to three stocks
and no data was offered for the Mongoloid female computation.)
**

**Compose
Your Own Regression**

Select easily measured structures of your body (such as
lower arm, fingers, foot). Then compose a calculation that
could be used to infer a person's height from the length
of these body parts. Compare and contrast your regression
to those given for femur and humerus. Which is more accurate
or consistent in obtaining heights from part length?

**(Measuring the length of bones in the hands and feet
is not as effective in inferring height as leg and arm bone
length. Though related, the former is much more variable.)****
