A Z-Score is a score that belongs to a standard normal distribution, where the Mean is 0, and the Standard Deviation is 1. With this z-score calculator, if you are working with a sample of data, you can introduce the Mean of your data and the Standard Deviation, and when you introduce a score to transform, you will get a Z-Score back. These scores are useful for many different purposes, such as investments and trading decisions, education and social sciences, or engineering. How to calculate Z-Scores could take sometimes a huge amount of steps, this calculator can make that process easier and faster. You will get a step-by-step explanation of the calculations a the end of your results.
Z-SCORE CALCULATOR
To be able to calculate z-scores from any other scores, you need to know:
1) The mean of your score data. This is the mean calculated from the sample where the scores you want to transform come from.
2) The standard deviation of your data.If you don't know how to do that, click on our Standard Deviation Calculator and we will do it for you.
Finally, introduce the score that you want to transform into the 'Score to transform' slot.
Step-by-step explanation - What if I need to learn how to calculate this by myself? Using a calculator won't prevent me from learning?
At the end of every calculation you will find a step-by-step explanation of the calculations made to get the Z-Score. The more you use this calculator, the more of those step-by-step explanations you will se, and the more likely is that you will learn the process with practice.
