WebA z-score is measured in units of the standard deviation. For example, if the mean of a normal distribution is five and the standard deviation is two, the value 11 is three standard deviations above (or to the right of) the mean. The calculation is as follows: x = μ + ( z ) ( σ) = 5 + (3) (2) = 11 The z -score is three. WebApr 12, 2024 · The area that is cut-off actually depends on the significance level. Say the level of significance, α, is 0.05. Then we have α divided by 2, or 0.025 on the left side and 0.025 on the right side. Now these are values we can check from the z-table. When α is 0.025, Z is 1.96. So, 1.96 on the right side and minus 1.96 on the left side.

WebFeb 28, 2024 · A Z-Score is a simple way of comparing values from two different data sets. It is defined as the number of standard deviations away from the mean a data point lies.
