Test the idea that the more 1 hour lessons taken results in less minor mistakes during a student of instructor C's driving test.

Conclusion

I have found that my hypothesis is true due to the strong negative correlation in the graph I produced. I have one anomalie on my graph this is probably due to not having enough results to analyze. I could make my results more reliable by using a bigger population using all the available data. The amount o lessons isn’t the only variable affecting the amount of mistakes there are other things such as the time of day, weather, what car etc. the results I have found aren’t very significant to the hypothesis.
