and precipitation. The extreme temperatures are based
on records through 1990 at the station listed and may
not agree with the state records.
(World Almanac 1998 p. 180)
1.
What is the largest amount of precipitation recorded
at any on the these site?
2.
What is the lowest extreme temperature recorded in this
table?
3.
Determine the average of the extreme temperatures for
each site.
The following is
a scatter plot of the average extreme temperatures and the normal precipitation
for each site.
3. Describe the
relationship between the average extreme temperature and the normal
precipitation indicated in the scatter plot.
4. The lower right
hand corner of this plot shows a cluster of five sites. Using both the
table and graph, identify these five sites and determine if there is
any relationship among them.
5. What observations
can you make about the relationship between the temperature and the
amount of rainfall in these five cities?
The following table

6. Which city has
the maximum percentage of sunshine?
7. Which three
cities have the least amount of rainfall?
8. Create a scatter
plot with the rainfall on the horizontal axis and the percent of sunshine
on the vertical axis.
9. Describe the
graph in your own words.
10. You can notice
a cluster of points in the lower right of the graph. Explain what you
know about these cities simply by their locations on the graph.
11. Draw a line
on the graph that represents the relationship among the data.
12. Determine the
slope of your line, and explain what it tells you about the relationship
between the data.
13. Describe the
x- and y-intercepts in words.
14. How can you
tell how well this lines fits the data?
