## Graphical Curve Fitting Using Experimental Data

In the previous exercise, you should have concluded that the data from Graph 1 could best be fit with a hyperbola. The general form of the hyperbola we will use is

Here *a* and *b* are the **parameters**, while *N _{avg}* and

*H*are the

**variables**. Substituting this equation back into equation 6, we get the following:

Exercise 9: Answer the following questions:

a) What is the reason for the 1 on the right-hand side of the expression?

b) What role does the value of *b* play? What happens as *b* is varied?

c) What role does the value of *a* play? What happens as *a* is varied?

d) Use the virtual graphs below to find what you feel are appropriate values for *a* and *b*.

e) Compare your values for *a* and *b* with your peers. How might you choose the most appropriate set of values for *a *and *b*?
