All development has moved over to this new platform and I will no longer be developing for this site (Blogger). Z value is negative indicating that the raw score is below the mean.This site has been deprecated Please visit the new home for these z-score calculators Given raw score x = 5, mean \(\mu\) = 3 and standard deviation \(\sigma\) = 1 With Cuemath, find solutions in simple and easy steps.īook a Free Trial Class Solved Examples on Z Score Calculatorįind the Z-score for a raw score of 5, mean 3, and standard deviation 1 and verify it using the z score calculator. Use our free online calculator to solve challenging questions. The calculator replaces \(\mu\) with u and \(\sigma\) by v. The formula for calculating the z score is given as follows: ![]() The standard deviation is represented by \(\sigma\). Divide the value obtained in step 1 by the standard deviation to get the z score.The mean is given by \(\mu\) while x denotes the raw score. Subtract the mean of the population from the given raw score.The steps to calculate the z score are as follows: If the z score is -2, it shows that the raw score is 2 standard deviations below the mean of the given data. Furthermore, if we have a z score that is equal to 1, it implies that the raw score is 1 standard deviation above the mean. Similarly, a negative z score denotes that the raw score is below the mean. A positive z score indicates that the raw score is above the mean. Z score can be both positive and negative. Step 4: Click on the "Reset" button to clear the fields and enter new values.Step 3: Click on the "Calculate" button to find the z score. ![]() Step 2: Enter the values of the raw score, the mean, and the standard deviation in the input boxes of the z score calculator.Step 1: Go to Cuemath’s online z score calculator.Use the steps given below to find the z score using the online z score calculator: To use this z score calculator, enter values in the input boxes. The z score tells us the number of standard deviations by which the raw score is above or below the mean of the data. Z Score Calculator is an online tool used to calculate the z score for the given mean, raw score, and standard deviation. Z scores are also called standard scores. Z Score is a measure that is used to describe the relationship between a raw score and the mean value of the given data set. Z Score calculator calculates the standard score for any raw score.
