#Section 3: Mathematics and Quantitative Ecology
  1. The standard error measures, roughly, the average difference between the statistic and the population parameter.
  2. The standard error is the estimated standard deviation of the sampling distribution for the statistic.
  3. The standard error can never be a negative number.
