Return to Functional Response Lab Page

Here is the data for the functional response lab that you are to use due to the rain-out of lab 7.

You must use the Fall 200 results

and, if you wish, you can also add the data from previous years.

The handling times are those reported by the experimenters. Their only use to you will be a comparison of the average actual handling time to the predicted Th gotten from the linearization. Use the predicted Th when calculating the predicted Pc values to use in the second graph.
