Although not specifically stated in Chapter 1, it seems reasonable that stature can be predicted from the lengths of many bones of the skeleton using regression equations. True or False? | True | 26-27 |

Like any other science, forensic anthropology has two basic methods: data gathering and data analysis. True or false? | True | 15 |

Anthroposcopy is the measurement of metric traits in human skeletons. True or false? | False | 16 |
