A negative z-score means it's lower than average. PCMark Memory Benchmark Favors GenuineIntel 298. The z-score allows you to compare data from different samples because z-scores are in terms of standard deviations.Ī positive z-score means the data value is higher than average. When you calculate a z-score you are converting a raw data value to a standardized score on a standardized normal distribution. You can calculate a z-score for any raw data value on a normal distribution. The z-score is the number of standard deviations a data point is from the population mean.
