To create a Graph Using Excel:
You have 2 columns of data.  The first column will be the X coordinate and the second Column will 
be the Y coordinate.  Highlight these two columns and then use your mouse and click on the
word Insert on the pull down menu.  Click on the Chart Option.  When this window opens, scroll
down to the scatter (x,y) graph option and highlight it.  Click the next button
at the bottom of the page.  This next page we won't need for this exercise so 
4 5 click on the next button again at the bottom of the page.  This next page
6 10 that shows up is where you can label your graph and axis.  Do this then 
7 13 click on the next button.  This final page just asks where you want your
5 6 chart located.  I would suggest placing it on a separate sheet from this
5 6.5 page.  Click on the option "object in" sheet #2.  This will place your graph
5.5 8 on sheet 2 of your spreadsheet (see at the bottom of the screen to click
4 4 between sheets. Click on the finsh button to place your graph into 
6.5 12 your spreadsheet.
5.9 11
5 7 Once you have created your graph you can change anything about it.  
6 9 You can remove data, change what the data points look like, add a trend line
5.5 7 change the background, change the axis fonts/scale etc.  Many of these 
4.8 6 changes can be made by clicking once on the graph then using the pull 
down menu at the top under chart
Once you have created your graph you can change anything about it.  
You can remove data, change what the data points look like (circles vs diamond), add a trend line
change the background, change the axis fonts/scale etc.  Many of these 
changes can be made by clicking once on the graph then using the pull 
down menu at the top under chart.  You can resize your graph by pulling on the
edge of it (after it has been selected).  Play with your graph a bit and try making it look different.
Change the font size on the Y axis by double clicking on the axis itself.  Then look at the options
and see how you can change the way the graph looks.  
Another option is to remove the Legend so the graph can be larger.  Do this by clicking on the legend 
and hitting delete or by going to the chart options and click on the "don't show" option. You only 
do this if you only have one group of data.
After you have played around a bit, try to put a trendline on the data.  You do this by making the graph active
and then using the chart option on the pull down menu.  Select "add trendline" and the linear option
Hit the ok button.  Now the best fit line should appear on your data. You can change the color, weight 
or style of the line by double clicking on it and then selecting what you want.  
Finally, Print off the first chart you  created and and the last chart.  To do this you can click on the graph
to make it active then hit print.  This will create a graph that is a full page in size.  To save paper, copy and 
paste your graphs to a new sheet (sheet 3) and then click on that sheet somewhere other than a graph.
Now when you hit the print option, you will print the whole sheet and not just the graph.
If you have problems working through this exercise, please come talk with me.  Don't wait till the day (or hour)
before the assignment is due to say something.  The Idea here is to help you learn some of the tools used
in science and to help you understand something about graphing data.  Oh…and the inturpetation part?
If I were to inturpret the data above…
