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 Navg 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?
