Suppose we would like to find the probability that a value in a given distribution has a z-score less than z = 0.25. To find this probability, we need to look up 0.25 in the z-table: The probability that a value in a given distribution has a z-score less than z = 0.25 is approximately 0.5987. Note: This could also be … Meer weergeven Suppose we would like to find the probability that a value in a given distribution has a z-score greater than z = -0.5. To find this probability, we need to look up -0.5 in … Meer weergeven 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. … Meer weergeven The following tutorials provide additional information about z-scores: 5 Examples of Using Z-Scores in Real Life How to Convert Z-Scores to Raw Scores How to Find Z-Scores Given Area Meer weergeven 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.
