Grading Rubric for Probability Experiment

4: Experiment problem clearly stated. Chart is set up with labels, data for 100 trials and is neatly presented on a spreadsheet. Calculations for theoretical probability and experimental probability are neat and correct. A short paragraph reflecting on the results is accurate and typed.

3: Experiment problem clearly stated. Chart is set up with labels, data for 99 – 75 trials are presented on a spreadsheet or graph paper. Calculations for theoretical probability and experimental probability are correct. A short paragraph reflecting on the results is accurate.

2: Experiment problem stated but not clear. Chart is set up with labels, data for 74 – 50 trials are presented on graph paper or plain white paper. Calculations for theoretical probability and experimental probability contain a few errors. A short paragraph reflecting on the results contains a few errors.

1: Experiment problem not stated. Chart is set up with no labels; data for 49 or fewer trials is presented on plain white paper. Calculations for theoretical probability and experimental probability contain several errors. No reflection paragraph on the results is given.
