Step 1:Identify the values and write them down. If the population mean of a data is 35 and standard deviation is 12, find the z-score for a raw value of 10. Although, you can find the normal score (z) using z test calculator above, you should also know how to find the z score using its equation. How to calculate z score?Ĭalculating z scores is not much difficult as it seems. Z value calculator uses the above equation to calculate zscore. Σ is the standard deviation of population. Z refers to the z-score or standard score, The formula of z score can be expressed as: Raw scores below the mean have negative standard scores and whereas those above the mean have positive standard scores. Z score or standard score is the number of standard deviations by which the value of a raw score is below or above the mean value of what is being measured or observed. In this space, we will discuss z score definition, z score equation, z-score table, and how to find z score without using z-score calculator. It takes raw score, population mean, and standard deviation from user and finds the z score with steps. Z score calculator is an online statistical tool that is used to calculate z score (standard normal score) for given values.
