Introduction to z score calculator
The z-score calculator helps to find the number of standard deviations for a particular data point from the population mean. Z-score holds a significant place in the statistics and can be computed on a normal distribution for any data value. However, manually it requires more effort to calculate. To resolve this problem, this z-score table calculator provide you immediate results.

What is the z score calculator
The Z-score calculator is an online tool that helps to compute standardized z-score for any particular value of X. If you know the value of mean (μ), experimental result (x), and the standard deviation (σ). If you get a negative z score, it means that the data value is lower than average. However, if you get a positive one, it means the data value is higher than average. The z value calculator gives the proper solution of the equation to understand the process.

How do to find the Z score on a calculator?
To compute the z-score on a regular calculator, follow the below-mentioned steps:
Calculate the mean by using calculator as μ = (∑x) / n.
Then Calculate the standard deviation by using the given formula (∑(x2) - (∑x)2/n) / n. In the case of sample data, the divisor would be n-1.
