    The mean or percentage is derived from a sample, so it is the sample statistic.
  79. •Standard Error (“SE”)
    measure of the variability in the sampling distribution

    Image Upload
  81. Standard Error of the Percentage
    • Image Upload
    • P + Q = 100
  82. The SE will be smaller for large sample sizes and larger with small sample sizes.
