Which of the following best explains how to find the test statistic for the one-sample sign test?

• A) Scores above the median are assigned a plus sign (+); scores below the median are assigned a negative sign (-); the test statistic is the number of pluses or minuses, whichever occurs most often.
• B) Scores are correlated as either positive (+) or negative (-); the test statistic is the extent to which scores are positively or negatively correlated.
• C) Scores are coded as being consistent (+) or inconsistent (-) with the null hypothesis; the test statistic is the number of pluses or minuses, whichever occurs most often.
