Cheek teeth of extinct primates. 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 were the subject of research reported in the American Journal of Physical Anthropology (Vol. 142, 2010). 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 Unknown Unknown Moderate Slight Unknown Moderate-heavy Moderate Slight Slight Slight Heavy Unworn Light-moderate Light-moderate Moderate Unworn 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. e. Construct a Pareto diagram for the data. f. Identify the degree of wear category that occurred most often in the sample of 18 cheek teeth.
