Question

Statistics teachers often debate the best order in which to
teach topics. One group of teachers likes to teach design
of studies first. Another group likes to begin with data

analysis. To see which order is more effective in prepar-
ing students for the AP Exam, an experiment was pro-
posed. A large group of teachers, each of whom teaches

two sections of statistics, volunteered to be a part of the
experiment. Each teacher will randomly assign one of
their classes to begin with design, and the other to begin
with data analysis. Which is the correct description of
this design?
a) The experimental units are the classrooms, the
blocks are the teachers, and the response variable
is the difference in average AP Exam score for each
teacher’s classes.
b) The experimental units are the teachers, there are no
blocks, and the response variable is the average AP
Exam score for each teacher.
c) The experimental units are the individual students,
the blocks are the classrooms, and the response
variable is each individual student’s AP Exam
score.
d) The experimental units are the individual students,
the blocks are the teachers, and the response
variable is the average AP Exam score for each
classroom.
e) The experimental units are the orders of topics, the
blocks are the teachers, and the response variable is
the average AP Exam score for all students who used
each order of topics.
