You Mean It's Not Free?

You will need to visit different websites in order to complete your webquest.  If you need assistance, check out the links on scatter plots, lines of best fit and linear equations.   

 1. Choose two(2) post high school institutions that interest you.  Look at any of the websites below to make you selection.

Colleges and universities: http://www.50states.com/college/

Community colleges: http://www.50states.com/cc/

 2. Research the cost of tuition (or tuition with room and board) for both institutions since 2001.  Note that tuition for 2001 may be listed as "2001-2002" or " '01-'02".  Hint #1:  Type in "tuition history" in the search area of the websites.  Hint #2:  If you can find the tuition cost for say '07-'08 and those numbers appear in the URL, change the year (say to 08-09) and see if 2008-2009 tuition costs are shown.  If not, just choose another institution. 

DATA DUE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

3. For each of your two institutions, create a scatter plot for your data.

Or this page: http://regentsprep.org/Regents/math/data/scatter.htm

4. Create a line of best fit for each of your two graphs.

Check out this YouTube video: http://www.youtube.com/watch?v=l8rbx-S5zGc

Or this page: http://regentsprep.org/Regents/Math/data/linefit.htm

5. State whether your line shows a) a positive correlation b) a egative correlation or c) no corelation (neither negative or positive)

6. For each graph, write a linear function that models the line of best fit.  Show all your work.  What is the slope of our line?  What is the y-intercept of your line?

GRAPHS AND EQUATIONS DUE!!!!!!!!!!!!!!! 

7. For each graph, predict how much you will pay in tuition (or tuition with room and board) for the 4 years you will attend.  That is, guess without using formulas.  Assume that you will be a full time student (12-15 credits/semester).  Be careful with your start and end dates!

8. Now do an actually computation of your 4-year tuition costs.  Compare it to your predictions for each graph.
