Central
Tendency and Box-and-whiskers
Review
In order to
better compare sets of data, it is
often necessary to analyze the data
using a variety of statistical
tools.
In this activity
you will construct a
box-and-whiskers graph with several
sets (boxes) displayed, and you will
also use values of central tendency
to give you a more complete analysis
of the data.
Procedure
The following
data are basketball scores for three
players in the last 10 home games.
-
Construct a
box-and-whiskers plot for each
of the players and their scores.
-

mean, median, and mode for each
of the four sets of data.
-
Answer the
analysis questions that follow.
