When the population distribution is normal, the population mean equals the population median. How good is the sample median as a point estimate of this common value? For a random sample, the estimated standard error of the sample median equals 1.25(s/√n). If the population is normal, explain why the sample mean tends to be a better estimate than the sample median.
