SAMPLE CONCLUSION #1 (Conclusive)
 
     My hypothesis was that the 3-wheeled car would have a greater speed than the 4-wheeled car because the three wheeled car has less mass. The average speed over five trials for the 3-wheeled car was 2.1 m/sec. The average speed for the 4-wheeled car over three trials was 2.5 m/sec. All of the trials were consistent, with a range of 2.5 m/sec to 3.5 m/sec for the 3-wheeled car and a range of 2.0 m/sec to 4.0 m/sec for the 4-wheeled car. Therefore, the data did not support my hypothesis, because the 4-wheeled car had a faster average speed.
     According to the data, the 4-wheeled car did have a higher average speed, so the mass was not a factor in affecting the speed of the car.

 

SAMPLE CONCLUSION #2 (Inconclusive)
 
     My hypothesis was that the 3-wheeled car would have a greater speed than the 4-wheeled car because the three wheeled car has less mass. The average speed over five trials for the 3-wheeled car was 2.1 m/sec. The average speed for the 4-wheeled car over three trials was 2.9 m/sec. All of the trials were inconsistent, with a range of 1.6 m/sec to 4.0 m/sec for the 3-wheeled car and a range of 2.0 m/sec to 4.0 m/sec for the 4-wheeled car. Therefore, I cannot determine if my hypothesis was correct or not because of the inconsistent data.
    From my basic observations of both types of car, the speeds appeared to be consistent. Therefore the inconsistencies of each trial could be due to timing errors.
