Global Warming Statistics
Follow these directions as you do your research:
1) Record data in a table (either using spreadsheet software, remembering to save, or making a neat chart
using a ruler and paper).
2) Find the mean, median, and mode of the data, and record these numbers in the
table as well. If using a spreadsheet and formulas are programmed, these numbers will appear in the table
automatically.
3)Analyze the data so far. Is there a pattern? Is there a noticeable increase in temperature for your
location over the time selected? If there are any drastic changes from one year to another, research to
see if there is a reason for this change (like a volcanic eruption).
4) Graph the data using graph paper and a ruler. Make a line graph with temperature vs. time, plotting
points for each piece of data, and then connecting the points with straight lines. Make three different sets
of lines on the same grid for mean, median, and mode of temperatures. Color code these sets and make a
key. Is there a noticeable trend in the graph?
5) Look at the graph and extrapolate what the mean, median, and mode temperatures will be for your
location five years from now, 10 years from now, and 20 years from now. How about in the year
2100?
6) Are you worried about global warming after making your predictions? Why or why not?
7) Prepare to present your findings to the class.
