SAMPLE CONCLISION #1 (Inconclusive)
     The hypothesis was that the 3-wheeled car would have a greater speed than the 4-wheeled car because it has less mass. The average speed over three 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. The data from the 3 trials was not reproducible because it ranged from 1.6 m/sec to 4.0 m/sec for the 3-wheeled car and from 2.0 m/sec to 4.0 m/sec for the 4-wheeled car. Therefore, it cannot be determined whether the data supported or did not support the hypothesis. 
     From visual observations, the speeds of both cars appeared consistent. Therefore, the inconsistencies of each trial may be due to timing errors.
 
 
                                     SAMPLE CONCLUSION #2 (Conclusive)
      The hypothesis was that the 3-wheeled car would have a greater speed than the 4-wheeled car because it has less mass. The average speed over three 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. The data for the trials was consistent, or reproducible, 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 the 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 either the mass was not a factor or higher mass causes a higher speed.
 
 
                                SAMPLE ERROR ANALYSIS #1 (If everything went right)
There we no major errors in either the 3 wheeled car or the 4 wheeled car. Both cars rolled straight, passed the 4 meter mark, and had speeds of at least 2.5 m/s. The performance of the cars met expectations.
     The improvement that would be most useful for these cars, would be to increase speed. In order to increase speed, friction between wheels and cars must be reduced to minimum this could be accomplished by using lubricant and increasing space between wheels and car. Also, the friction between the wheels and the ground should be at an optimal level.
 
                          SAMPLE ERROR ANAYSIS #2 (Something goes wrong)
There are some major errors in all 3 trials for both the 3 wheeled and 4 wheeled car. Both cars did not roll straight and did not pass the 4 meter mark, with speeds of below 1m/s. In all three trials for both cars, it turned left at the 1 meter mark; in addition, it appeared that the left rear wheel had too much friction and stopped rolling. The performance of the cars did not meet expectations.
