Confidence Intervals for a Population Median

  • The methods for calculating confidence intervals for a population median assume that our data come from an SRS and will give trustworthy conclusions only if this condition is met.

  • These methods make no assumptions about the distribution your data comes from.

  • If the $t$-procedures cannot be trusted to estimate a population mean, these procedures may be used to estimate a population median instead.

  • Each interval is "symmetric" about the sample median in that the end points of the interval are the same number of points above and below the sample median.
