What's the difference between Bell curve and Gaussian distribution

  1. May 21, 2013 #1
    I was looking to the definition of the Bell curve, and the Gaussian distribution, but I don't see any difference when we represent them in a graph. Both have the same Bell curve. What is the difference between the Bell curve and the Gaussian distribution?

    I found the solution.

    The bell curve is the graph of the PDF of the gaussian distribution

    Often bell curve and Gaussian distribution are used interchangeably with normal distribution. But sometimes people use bell curve to mean anything which looks kind of like a bell: smooth, with one lump in the middle, two inflection points, and rapidly-decreasing tails on either end.

    I usually see Gaussian used in physics, normal used in statistics, and bell curve used in pop-science articles. But that's just a guideline.
