8.127 Median as point estimate When the population distribution is normal, the population mean equals the population
Question:
8.127 Median as point estimate 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 standard error of the sample median equals 1.251s>1n2. If the population is normal, explain why the sample mean tends to be a better estimate than the sample median. (Note: Both estimators are unbiased.)
