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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
