The Z-score or standard deviation classification system. Tests of Significance Once sample data has been gathered through an observational study or experiment, statistical inference allows analysts to assess evidence in favor or some claim about the population from which the sample has been drawn. The z-value usually indicates the elevation of a feature above the ground surface. The t value that we obtain can be related back to a t-distribution in order to estimate the probability of obtaining a value this far from the population mean or farther.
