As to a norm distribution data \(X\), how to convert its distribution to standard normal distribution? In this tutorial, we will introduce you how to do.
What is Normal Distribution?

How to convert a normal distribution data to standard normal distribution?
As to standard normal distribution, it need the mean of \(X\) is 0, the variance of it is 1.
We can do like this:
\[\hat{X}=\frac{X-\mu}{\sigma}\]
where \(\mu\) is the mean value of \(X\), the \(\sigma\) is the standard deviation of \(X\). \(\hat{X}\) will be a standard normal distribution.
