![]() ![]() And, because we know that z-scores are really just standard deviations, this means that it is very unlikely (probability of \(5\%\)) to get a score that is almost two standard deviations away from the mean (\(-1.96\) below the mean or 1.96 above the mean). Thus, there is a 5% chance of randomly getting a value more extreme than \(z = -1.96\) or \(z = 1.96\) (this particular value and region will become incredibly important later).

We can also find the total probabilities of a score being in the two shaded regions by simply adding the areas together to get 0.0500. ![]() What did we just learn? That the shaded areas for the same z-score (negative or positive) are the same p-value, the same probability. \( \newcommand\), that is the shaded area on the left side.
