How to find the p value for Z score
What is the p (Probability) value for Z score? ((also called a standard score)) it gives you an idea of how far from the mean a data point is. But more technically it's a measure of how many standard deviations below or above the population mean a raw score is. A z-score can be placed on a normal distribution curve. The p-value is the probability that you have falsely rejected the null hypothesis (a hypothesis that says there is no statistical significance between the two variables in the hypothesis). Z scores are measures of standard deviation. For example, if a tool returns a Z score of +2.5 it is interpreted as "+2.5 standard deviations away from the mean". P-values are probabilities. A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. A negative z-score reveals the raw score (an original datum that has not been transformed) is below the mean average, In statistics, the standard score is the signed fractional number of standard deviations by which the value of an observation or data point is above the mean value of what is being observed or measured.
