Starting with what is an outlier; An outlier is simply an observation point that is distant from other observations. They occur because of variability in the measurement, and it simply indicates an experimental error.

I knew that I didn’t face outliers because I did not record an abnormal observations. And any thing that was far far away from the average time and speed was considered an outlier and was removed from our collected data as a team. Some times outliers occurred either because the paper helicopter did not make it way to the floor correctly, or because the timer was not started correctly. Those were the two main outliers that I faced.

  1. What an excellent piece.

    Your results table now meets all the criteria for the Raw Data badge which I have now unlocked for you. Well done!

    Let’s move your graph to a new post. We’ll hand draw one too as it is a skill you’ll need for next year.

  2. PS- Do I owe you the Radiation badge? And if I do can you show me the piece of work for which you feel I should award it?
