Genealogy research. The Journal of Family History (Jan.

2010) investigated the genealogy of a certain Korean clan.

Of interest was whether or not a family name continued into the next generation in the clan genealogy (called a continued line) or dropped out (called a dropout line). Sideby-

side pie charts were used to describe the rate at which certain occupational titles of clan individuals occurred within each line type. Similarly constructed MINITAB bar charts are shown on p. 67.

a. Identify the two qualitative variables graphed in the side-by-side pie charts.

b. Give a full interpretation of the charts. Identify the major differences (if any) between the two line groups.
