In this blog let us understand the basics of the Z-score. This is useful to know *how the data is distributed*.

Let us start.

**Examples:**

Dataset A is : 10, 12, 14, 16.

Dataset B is: 10, 200, 350, 600.

As you can see, both the mean of B (290) and the standard deviation of B (13) are higher than that of A.
