This document provides information and examples about analyzing line plots and data. It includes instructions on how to construct a line plot to represent grade data for 5 students. It defines key terms used to describe line plots such as outlier, range, cluster, and gaps. Examples are provided to calculate the range between movie grossing values and identify gaps and clusters. Students are assigned homework problems analyzing additional line plot data.

4. OUTLIER(S): Data values that are much SMALLER
or LARGER than the rest.
RANGE: The DIFFERENCE from the smallest to the
largest values.

5. CLUSTER: A group of 3 OR MORE values that are
bunched up close together.
GAP(S): LARGE spaces between values.

8. a) range = $938,729,768 ­ $453,373,048
= $485,356,720
b) Titanic
c) 1st cluster: Star Wars, Harry Potter, Sixth Sense
2nd cluster: Independence Day, Star Wars: Return of the Jedi, Lion King
d) between Star Wars: New Hop and Titanic
= $938,729,768 ­ $720,211,976
= $218,517,792
e) no relationship
f) half the movies have made between $4.5 million and $5 million.

9. BONUS: The current top 12 list of all
time top grossing movies is different
now then it was in 2002, in the list you
just saw. See how many your group
can come up with in the next 10
minutes. Write them down and the
winning group will receive 3 bonus
marks each on the next test.
