WebJun 24, 2024 · Z-scores generally range from -3.0 to +3.0. For bell shaped distributions, the empirical rule says 99.7% of all the data values have z-scores between -3.0 and +3.0. We consider any z-score that is either less than -3.0 or greater than +3.0 to be an outlier. Comparing Similar Types WebZ-Score Table. A z-table, also known as the standard normal table, provides the area under the curve to the left of a z-score. This area represents the probability that z-values will fall within a region of the standard normal distribution. Use a z-table to find probabilities corresponding to ranges of z-scores and to find p-values for z-tests.

Normal Distribution: Find Probability Using With Z …

Suppose we would like to find the probability that a value in a given distribution has a z-score between z = 0.4 andz = 1. First, we will look up the value 0.4in the z-table: Then, we will look up the value 1in the z-table: Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the … See more Suppose we would like to find the probability that a value in a given distribution has a z-score less than z = 0.25.
