Z Score Calculator allows you to easily calculate Z-Score by taking inputs of row score, population mean, and standard deviation.
Z Score Calculator is an easy-to-use and 100% accurate online tool to calculate Z-score. Just enter the row score, the population mean, and standard deviation and hit the "Calculate" button. As a result, the tool will display the Z-score result. Also, it is very much fast and efficient. The manual calculation is a bit confusing and becomes very difficult when dealing with large numbers. So, use the calculator to save your time and effort.
In simple words, the Z score denotes the difference between the data points of raw scores from the mean value. You can get the number of standard deviations of a data point above the mean value. Hence, it is also known as Standard Score, Normal Score, or Z-Value.
Now, as you have learned about the Z Score let's understand how you can calculate the Z Score.
According to statistical analysis, we use this formula to calculate the Z Score:
Z = Z Score
x = Raw Score
μ = Mean
σ = Standard Deviation
Hence, in order to calculate the Z score or standard score, firstly, you need to get the value of raw score, mean and standard deviation. After getting the values just put them in the formula and you will get the Z-score easily.
Z Score Calculator takes these required values from the user and determines the final result instantly. The same statistical formula is being used here.
Let's make the calculation part crystal clear by understanding the process with an easy example.
Here, we have the following values:
Raw score, x = 20
Mean, μ = 15
Standard Deviation, σ = 5
Put these values in the formula and evaluate the expression.
Finally, we get Z Score value = 1.
Follow these simple steps below to use the tool without any problem:
Above all information was about the highly useful online Z Score Calculator. Also, it's a simple tool with a bunch of benefits. Just type or paste your values and get instant output. This tool is great for making your statistical calculations easier. Also, it will help you to solve problems on probability and compare different sample spaces.
