I am taking a statistics course and we are studying Random Variables and Probability Models right now. I am learning a lot about the probability functions for different variables, but I am having a really hard time determining which model to use for any given question that is assigned. We have covered:

  • Discrete Uniform
  • Hypegeometric
  • Binomial
  • Negative Binomial
  • Geometric
  • Poisson

Does any one have any tips on knowing which one is appropriate to use in which situations?

    Dont apologize. You asked a question about concept. Abstract. They are broad by default. I respect you a hell of a lot more than the person who asks a specific question that they drew from their evening homework. And I lose respect for anyone who mocks you for asking a question that demands conceptual explanation, because if doing that is too difficult for them then they probably dont understand the material as well as they want to get credit for.2013-02-24
