Central limit theory

    Cards (11)

    • Define the central limit theory
      If you take samples from a distribution and calultate the sample means.
      Plot the sample means and the distribution approximates a normal distribution.
    • What is the graph produced by the central limit theory
      The sampling distribution of the sampling mean
    • What are the types of uniform distribution
      Discrete and continuous
    • What happens to the sampling distribution of the sampling means as sample size increased
      It gets closer to a normal distribution
    • What is the recommemded sample size for the central limit theory
      Over 30
    • What is the significance level

      This is the probability that the null hypothesis is true
    • What is the symbol for the significance level
      Alpha
    • What is the null hypothesis symbol
      H 0
    • What is the null hypothesis
      That there is no significant difference
    • What is H1
      The alternative hypothesis
    • What is the P-value
      The probability of observing the outcome or any outcome which is more extreme
