The characteristics of cheek teeth e g molars can provide anthropologists
The characteristics of cheek teeth (e.g., molars) can provide anthropologists with information on the dietary habits of extinct mammals. The cheek teeth of an extinct primate species was the subject of research reported in the American Journal of Physical Anthropology (Vol. 142, 2010). These data are saved in the CHEEKTEETH file. A total of 18 cheek teeth extracted from skulls discovered in western Wyoming were analyzed. Each tooth was classified according to degree of wear (unworn, slight, light-moderate, moderate, moderate-heavy, or heavy). The 18 measurements are listed here.

Data on Degree of Wear

Unknown ……….. Slight

Unknown ……….. Slight

Unknown ……….. Heavy

Moderate ……….. Unworn

Slight ………….. Light-moderate

Unknown ……….. Light-moderate

Moderate-heavy ……… Moderate

Moderate ……….. Unworn

Slight ……………….. Unknown

a. Identify the variable measured in the study and its type (quantitative or qualitative).

b. Count the number of cheek teeth in each wear category.

c. Calculate the relative frequency for each wear category.

d. Construct a relative frequency bar graph for the data.
