Expected Value of Distribution on Histogram: T/F

  1. Jul 5, 2011 #1
    1. The problem statement, all variables and given/known data

    4: (T/F) The expected value of a distribution always occurs at the center of the tallest bar on the histogram.

    2. Relevant equations

    (no equation necessary for it is T/F)

    3. The attempt at a solution

    I believe this is false for the expected value can be definite or indefinite.

    If you believe it is false, why don't you make a simple histogram that illustrates that it isn't true? That would settle it and you wouldn't be guessing.

    Yup, just make up a histogram and test it.
    Easy as pie in Matlab, or even just by hand.

    -> The thing to do is calculate the mean value of the histogram, and check if that is in the "highest bar".
