Standard error
  1. Middle bar always population mean
    1. SE = Does samples vary from population mean
      1. 2 samples from population may have differing SE
        1. Sampling error
          1. variation from population
          2. Is difference due to sample variation or manipulation
            1. For each sample there is a mean (circle in the middle) and an upper and lower interval (adjoining lines) which show how scores difference from population mean
              1. Samples whose upper interval and lower interval do not at all fall on population mean don't contain 'true value'
              2. Middle bar always population mean
                1. SE = Does samples vary from population mean

                        2. SE is the standard deviation of a sampling distribution
