The z Score Probability calculator computes the area under the Normal Distribution curve to the left and right of a z SCORE. /attachments/3c86f2fd-2144-11ec-993a-bc764e203090/Normal Distribution.png Probability & Normal Distribution This equates to the probability of an event with a lesser z SCORE.

INSTRUCTIONS: Enter the following:

(z) This is the z SCORE.

Area Under the Normal Curve: The calculator returns the area under the Normal Distribution curve to the left and right of the z SCORE. This is equivalent to the probability of an event with a z SCORE less (left) than the entered value or greater (right) of the entered value. It ranges from 0.00001 to 0.99999.

The z SCORE Probability function is a prominent feature with other statistical functions in the College Level Statistics Calculator (Stat Calc).
