Estimating the OHHS population from a sample

  1. Using the population of students in this room estimate the number of students at the OHHS main campus. Show your calculations.
  2. Obtain the actual student count from the OHHS receptionist, Mrs. White.
  3. Calculate the percentage error in your estimates using this formula:

    % error = 100*[(estimated population - actual population) / actual population]

  4. Explain how the count of students in the room (the sample) could cause a bad population estimate?
  5. How could you minimize that error in estimating the student population?
  6. Could you ever eliminate the error? Explain your reasoning.
