Z-Score Calculator

Z-score Calculator (or Z Table Calculator or Z-score Probability Calculator) is an online calculator designed specifically to solve the problems of z- score. In this we need 'Standardized Random Variable, X', 'Population Mean (µ)', 'Population Standard Deviation (s)' and using these three parameters we can easily determine the value of Z-score (or Standard Normal Score).
 
Step to follow:
Step 1: First enter the value of Standardized Random Variable in first text box.
Step 2: After this plug in value of Population mean (µ) in provided text box.
Step 3: Now put value of Population Standard Deviation (s) in respective text box.
Step 4: After providing all inputs click ‘Calculate’ button and z - score value will be displayed in Z - score / Standard Normal Score text box.
Example: Calculate the z-score when Standardized Random Variable is 12, Population mean is 2 and Population Standard Deviation is 10?
Step 1: Enter the value of Standardized Random Variable (X) = 12, in given text box.
Step 2: Plug in value of Population mean = 2, in its provided text box and,
Step 3: Put value of Population Standard Deviation = 10, its text box.
Step 4: Now, click ‘Calculate’ button and output will be displayed as 1 in the output  text box.
