Lab report - Arm span/height

  1. Hi!

    I have to do a lab report for AP2. It is given from the state and they want to make sure we know how to do scientific method. I have the thing finished except for one question. It asks for my hypothesis and then asks for a rationale.

    My hypothesis is that arm span and height do not match. But I cannot figure out what to write as to my reasoning for this. I did write because everybody is different but I am not happy with this answer.

    Does anybody have any clue as to what I would write?

    I'm not sure if it's true or not, but just guessing, I'd say no as you did.

    It seems to me that part of the height is determined on the length of the femur. If the arm span doesn't include the longest bone in the body, one would think that the arm bones couldn't equal the length of the whole person.

    Then again, the human body is amazing. I'd be curious to know if this is really true.

    Good luck to you!
