Sign Test for Median (Single-Sample & Paired) – Practice Quiz

Use one-sample and paired sign tests for continuous medians and directional changes. Prerequisites: binomial probabilities, medians and paired differences. Encode signs, state tie conventions, calculate exact one-sided and two-sided tails, and use continuity-corrected normal approximations when appropriate. Original service and training scenarios examine discreteness, dependence, magnitude information and the distinction between a median of differences and a difference of medians.
