The concept Statistics

Chapter One:

  Random events: the relationship between events and operations

  Probability:

    First, the classical probability and geometric probability

    Second, important official (8 large)

  Sample space

Chapter two:

  Random variables (random event)

    Discrete random variables

    Continuous random variables

  Distribution function of the random variable

    Discrete distribution function

  Probability density function

    Distribution function (for f (x) from negative infinity to the integration of x)

    Concept density (f (x) = P (x))

  Distributed random variable type (type determines the distribution of the probability density, or be able to find the concept of density distribution function)

    Discrete:

      1,0-1 distribution

      2, binomial distribution

      3, Poisson distribution

      4, geometric distribution  

      5, hypergeometric distribution

    Continuity

      1, evenly distributed

      2, exponential distribution

      3, Shota distribution

  Distribution function of the random variable

    Discrete

    Continuous
