The Z-value is a test statistic for Z-tests that measures the difference between an observed statistic and its hypothesized population parameter in units of standard error. For example, a selection of factory molds has a mean depth of 10cm and a standard deviation of 1 cm.
Z-Scores; Empirical Rule. Suppose x is a value, or âscoreâ. We want to compare x to a data set (or population) with mean (or Î¼) and standard deviation s (or Ï). x may or may not be a part of the data set. Define the z-score for x as or. â¢ The z-score tells us how many standard deviations x is from the. mean. â¢ The further z is from zero, the more âatypicalâ x is, relative to. the given data set. In fact, the âempirical ruleâ states that for.
