Paper Airplane Design
and Statistical Analysis

And the winner is........
| Purpose: |
| 1. | To accurately follow airplane designs |
| 2. | To test performance of individual airplane design |
| 3. | To determine which design gives consistently long, stable flights |
| 4. | To become familiar with and see the use of the following terms |
|
a. mean b. deviation c. variance d. signal/noise ratio e. parameter |
|
| 5. | To apply statistical methods to data for the purpose of determining the "best" design model |
| 6. | To produce one "best" design model and defend the choice of that model |
| 7. | To compare new chosen design with your last flight data |
| Terms to Know: |
| 1. | Statistical analysis |
| 2. | Parameter |
| 3. | Bell Curve (normal) |
| 4. | Skew |
| 5. | Bias |
| 6. | Mean |
| 7. | Variance |
| 8. | Deviation (standard) |
| 9. | Signal ÷ Noise ( S/N ratio) |
| 10. | Robust design |
| Airplane Design Parameters (X) |
| a. | weight distribution ( center of gravity or c of g ) |
| b. | stabilizer |
| c. | nose length |
| d. | wing angle (area of wing) |
Each parameter has three (3) variables ( N ). Thus, the formula used to determine the number of possible combinations for airplane design is
XN = 43 = 64 possibilities
Utilizing a rotating statistical design matrix, we will test samples using nine (9) experimental design patterns to be issued by the instructor. |
|
Using a S/N ration, select the more robust design. |
| Procedure: |
| 1. | Obtain lab sheets, statistical terms, and materials for airplane bodies |
| 2. | Accurately follow airplane designs, labelling each design with experiment number and your name |
| 3. | Fly plane, measure, record flight distances in meters |
| 4. | Obtain all pertinent data from all physics classes |
| 5. | Obtain all statistical results and graphs from teacher |
| 6. | After analysis of data, choose, build, and test "best" design |
| 7. | Defend your choice of design in written discussion and conclusion |
