How to calculate z score value?

According to the formula for the calculations of the z score, it requires an Experimental result (x),Mean value (μ) and Standard deviation (σ).

Suppose that:

$$\text{Experimental result(x)}\;=\;120$$

$$\text{Mean value(μ)}\;=\;100$$

$$\text{Standard deviation(σ)}\;=\;10$$

Formule:

$$z\;=\;120\;-\;\frac{100;}{10}$$

$$z\;=\;\frac{120-100}{10}$$

$$z\;=\;\frac{20}{10}$$

$$z\;=\;+2$$
