Mixed gender decision-making groups. In business, a group of executives is often assigned to make key decisions. The American Journal of Political Science (April 2014) pub- lished a study on a woman's impact on mixed-gender delib- erating groups. The researchers randomly assigned subjects to one of several 5-member decision-making groups. The groups' gender composition varied as follows: 0 females, 1 female, 2 females, 3 females, 4 females, or 5 females. Each group was then randomly assigned to utilize one of two types of decision rules: unanimous or majority rule. Ten groups were created for each of the 6 × 2 = 12 combina- tions of gender composition and decision rule. One vari- able of interest, measured for each group, was the number of words spoken by women on a certain topic per 1,000 total words spoken during the deliberations. a. Why is this experiment considered a designed study? b. Identify the experimental unit and dependent variable in this study. c. Identify the factors for this study. Give the levels of each factor. d. How many treatments are in this study? List them.

Mixed gender decision-making groups. In business, a group
of executives is often assigned to make key decisions. The
American Journal of Political Science (April 2014) pub-
lished a study on a woman's impact on mixed-gender delib-
erating groups. The researchers randomly assigned subjects
to one of several 5-member decision-making groups. The
groups' gender composition varied as follows: 0 females,
1 female, 2 females, 3 females, 4 females, or 5 females. Each
group was then randomly assigned to utilize one of two
types of decision rules: unanimous or majority rule. Ten
groups were created for each of the 6 × 2 = 12 combina-
tions of gender composition and decision rule. One vari-
able of interest, measured for each group, was the number
of words spoken by women on a certain topic per 1,000
total words spoken during the deliberations.
a. Why is this experiment considered a designed study?
b. Identify the experimental unit and dependent variable
in this study.
c. Identify the factors for this study. Give the levels of
each factor.
d. How many treatments are in this study? List them.
