## How can I calculate a probability using a Z-score?

A z-score measures exactly how many standard deviations above or below the mean a data point is. Here's the formula for calculating a z-score: Here's the same formula written with symbols:

## Z-Score: Definition, Formula and Calculation

The probability is the area below the Normal distribution's curve. For a score of z = 3.16, the area under the Normal distribution from − ∞ σ to 3.16 σ is ≈ 1 (this is the probability). Note this an

## Z-Score: Definition, Calculation & Interpretation

Using the z-table below, find the row for 2.1 and the column for 0.03. Intersect that row and column to find the probability: 0.9834. Therefore p ( Z < 2.13) = 0.9834. Noting that

## Z-Scores – Math For Our World

The probability that a standard normal random variable (z) is greater than a given value (a) is easy to find. The table shows the P(Z a) = 1 – P(Z < a). Suppose, for
