A standard type of problem in basic statistics is to calculate thez-score of a value, given that the data is normally distributed and also given themeanandstandard deviation. This z-score, or standard score, is the signed number of standard deviations by which the data points' value is abov...

A z-score is also a quick way to apply the empirical rule. For example, you can quickly check if 95% of the values in a data set are within two standard deviations by checking the percentage of values with z-scores between -2 and 2. How do I calculate z-scores? You calculate the...
Step 1:To calculate the z-score for a single data pointx, we must first identify two additional values: The mean,μ, of the distribution from which the data point was sampled The standard deviation,σ, of this same distribution Step 2:Apply the z-score formula:z=x−μσ ...
This calculator will tell you the two-tailed area under the standard normal curve, given a Z-score (i.e., the two-tailed probability from +/- the Z-score to infinity on both tails of the distribution). Please enter the necessary parameter values, and then click 'Calculate'. ...
