Key:
“1 6” means $16.00.
Stem and
leaf plots tend to be available in more advanced statistical packages (such as
SAS or SPSS). For our purposes, we can simply create stem and leaf plots as a
word processing document like the one that is shown above.
You will
answer these questions below:
1. What is
the smallest amount of student weekly earnings in the above plot? What is the
largest amount?
(Insert you

2. Make a
new stem and leaf table by ordering the remaining rows. The median of a set of
data is the middle score. Find the median weekly earnings of the students in
the stem and leaf table.

3. The mean
of a set of data is the ordinary arithmetic average. Just add up the data and divide
by the number of data points. Find the mean of the weekly earnings of the
students.
