Finding where the data is uniform

  1. Feb 3, 2012 #1
    Hey guys,

    I have a bunch price observations. I would like to know whether some subset of my observations is uniformly distributed (or close to being uniformly distributed). How could I go about testing this?

    Your question isn't precise. It could mean that you want to test the hypothesis that the data values which fall in a certain interval are uniform. (For example, you could be asking "Are the birth weights of babies that fall between 6 lbs and 8 lbs uniformly distributed?") Or you could be asking if a subset of the entire collection of data is uniform. (For example, you could be asking "Is the subset of infant birth weights defined by babies who were born on Thursday uniformly distributed".

    Regardless of which of those types of questions you are asking, If you are going to consider a uniform distribution, you have to define it's range.
