Question

In archaeology, the depth (below surface grade) at which artifacts are found is very important. Greater depths sometimes indicate older artifacts, perhaps from a different archaeological period. The figure below is a back-to-back stem plot showing the depths of artifact locations at two different archaeological sites. These sites are from similar geographic locations. Notice that the stems are in the center of the diagram. The leaves for Site I artifact depths are shown to the left of the stem, while the leaves for Site II are to the right of the stem.

 

(c) At Site II, there is a gap in the depths at which artifacts were found. Does the Site II data distribution suggest that there might have been a period of no occupation?
O Yes, it would appear that Site II probably was unoccupied during the time period associated with 100 to 120 cm.
O Yes, it would appear that Site II probably was unoccupied during the time period associated with 70 to 100 cm.
O No, the distribution suggests that the area was likely occupied at all times.
O Yes, it would appear that Site II probably was unoccupied during the time period associated with 50 to 80 cm.

Expert Solution
Step 1

From the given information

  • In Site 1:
    • The least depths of artifact at Site 1 is 25 cm.
    • The greatest depths of artifact at Site 1 is 110 cm.
    • Distribution of depths of artifact at Site 1 is uniform distribution because that is fairly uniform shape for a gap.
  • In Site 2:
    • The least depths of artifact at Site 2 is 20 cm.
    • The greatest depths of artifact at Site 2 is 125 cm.
    • Distribution of depths of artifact at Site 2 is strongly skewed to right.
