How many organisms (marked beans) were recaptured for each trial of the procedure?

Using the Lincoln-Petersen equation, estimate your bean population and record your final estimate for each trial of the procedure. Be sure to show your work.

Calculate your percent error for each trial. Be sure to show your work.

Post-lab Questions

  1. Describe the experimental design you carried out for estimating your bean populations.

  2. How accurate were your estimates of the population size of beans you used?

  3. What type of difference did you find between the percent error in your first and second trial of bean population sizes?

  4. What do you think the strengths of this method are? And the weaknesses?

  5. What could be done to help improve this method, if anything?
