WebThis analysis of x i − m 0 under the three situations m = m 0, m > m 0 , and m < m 0 suggests then that a reasonable test for testing the value of a median m should depend on X i − m 0 . That's exactly what the sign test for a median does. This is what we'll do: Calculate X i − m 0 for i = 1, 2, …, n. Define N − = the number of ...
