The Z Score Calculator calculates the provided Mean, raw score and SD. It determines if the mean Value is above or below the mean Data.
Using our Z Score Calculator is easy and without any hassle. Input the values in the required boxes.
How to use our Z Score Calculator ?
Using the AllCalculator.net Z Score Calculator is the easiest.
- Open the Z Score Calculator.
- Input the raw score, mean and Standard Deviation in the boxes stated in the Calculator.
- Now tap on Calculate to calculate the z score of the input you gave to the Calculator.
- If you need to calculate multiple times, use the reset option.
How does the Z Score Calculate? Does it use the formula?
Z=X-μ/σ
If the Z Score is positive, the raw score will be more than the Mean; similarly, if it's less, the raw score is below the mean Value.
If the raw score is one, then the Standard Deviation is above the Mean. However, if the score is -2, the Standard Deviation is. Below is the Mean for any given data set. Some steps for calculating the z score are
- Minus or deduct the Mean of the population of the given raw score.
- μ-Denotes the Mean, and x denotes the raw score.
- Divide the obtained Value by 1 of the Standard Deviation. It is used to determine the Z Score, and it is represented by σ
The Calculator will replace μ and σ with u and v.
Let's understand this with one example.
Example.
Calculate or determine the Z Score for a raw score of 5 and a mean value of 3. The Standard Deviation will be valued at 1. Use our Z -Score Calculator to verify it.
Provided details
X=5
μ=3
σ=1
Now the Calculator will use the Same formula and compute the values using the formula.
Z=X-μ/σ
5-3/1=2
Now the Value is two meaning the Standard Deviation is above the Mean.
Conclusion
Z Score Calculator calculates the Mean and Raw Score values. It can determine if the Value is above or below the Mean.
