**ArcGIS Help 10.1 What is a z-score? What is a p-value?**

Z-scores may also be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean.... In short, just subtract the values in this table above from 1. So for a z-score of -2, with a p-value of 0.5, that gives (1- 0.9798) = 0.0202. You will get a negative z-score when $ x $ is less than $ \mu $ in the following equation:

**Negative P-Values Biostar S**

State the values of the raw scores and Z-scores. A positive Z-score indicates a score that is higher than the mean. A negative Z-score indicates a score that is less that the mean. The larger the Z-score, the greater difference there is between the score and the mean.... The value in the intersection of the row and column is the area under the curve between zero and the z-score looked up. Because of the symmetry of the normal distribution, look up the absolute value of any z-score.

**P value for a negative Z score? StatsXchanger**

have to look up the z-score of the sample mean in the table of z-scores to find out what percentage of the standard normal distribution falls between your sample z -score and negative infinity.... Negative z-Scores and Proportions The table may also be used to find the areas to the left of a negative z -score. To do this, drop the negative sign and look for the appropriate entry in the table.

**How to Report Z-Score Results Sciencing**

The textbook also has an example where $\mathbb P(Z\geq3.9) = 0.000048$; can somone Stack Exchange Network Stack Exchange network consists of 174 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.... Both z-scores and p-values are associated with the standard normal distribution as shown below. Very high or very low (negative) z-scores, associated with very small p-values, are found in the tails of the normal distribution.
