P(y) from z

The z Score Probability calculator computes the area under the Normal Distribution curve to the left of a z SCORE.      Probability & Normal Distribution  This equates to the probability of an event with a lesser z SCORE.

INSTRUCTIONS: Enter the following:

• (z) z SCORE

Area Under the Normal Curve (P): The calculator returns the area under the Normal Distribution curve to the left of the z SCORE.  This is equivalent to the probability of an event with a z SCORE less than 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).
