To calculate a z-score, subtract the mean from the raw score and divide that answer by the standard deviation. (i.e., raw score =15, mean = 10, standard deviation = 4. Therefore 15 minus 10 equals 5. 5 divided by 4 equals 1.25. Thus the z-score is 1.25.) Lay people are sometimes uncomfortable with z-scores for a couple reasons.

Z-Score to Percentile Calculator Enter a z-critical value and get the area under the normal curve (a percentage). Selecting two-sided provides the area above Z and below -Z. Download this calculator in an excel file or take a Crash course in Z-scores

Years ago, when laboratories were beginning to assay controls, it was easy to calculate a mean and use that value as the "target" to be achieved. For example, given the following ten analyses of a control material - 90, 91, 89, 84, 88, 93, 80, 90, 85, 87 - the mean or Xbar is 877/10 or 87.7.

Compare two sample proportions using the 2-sample z-test. P-values can be calculated for one or two-tailed comparisons and are compared results to a specified significance level.
