WebbThe Z score is a measure of how many standard deviations a data point is away from the mean. Z scores rely on the standard normal distribution (or Gaussian) which has a mean of 0 and a standard deviation of 1. It is primarily used to test for differences between means for large samples. WebbTwo-tailed tests deal with both tails of the distribution, and the z-score is on both sides of the statistic.For example, Figure 9.4 illustrates a two-tailed test. A hypothesis like “the mean is not equal to 10” involves a two-tailed test because the claim is that the mean can be less than 10 or it can be greater than 10. hill country land improvement
