How to gather the data and create the graphs.
First, go to http://www.ncdc.noaa.gov/cag/time-series/us collect the data. Select parameter,
select Annual, select years, select state, select city or region. Click Plot.
Next, look for the Download buttons, click on the excel icon. This will give you a list,
which you can copy and paste into the excel spreadsheet. However, you will need to
delete the extra info in each cell, so that you only have the temp or precip value.
To calculate the average for each variable, highlight the 50 cells in each column.
In the upper right side, find AutoSum. Click on the arrow for a menu, select Average.
This will put the average at the bottom of the column.
Next, in a new column, type into the cell =(column number row number average).
For example, in the diagram below, 1965 high temperature data starts in column C, row
7, and the average for the 50 years is 79. Thus, you would type into that cell, =(C7-79),
and hit enter. Now, using the small black square in the lower right corner of the cell,
click and drag down to the last row of data. This will copy the formula and adjust for the
cell change, giving you the difference from the 50 year average.
To graph this, highlight that column, then select the insert menu, click on line graph, and
select 2-D line.
This will put a graph on your screen, which you can move to a different part of the
spreadsheet. Do this for each of the 3 variables.
Lastly, in a Word document, write your analysis of what this data is telling you about the
changes in the past 50 years.
