The z-score converts a non-standard distribution to a standard distribution in order to find the probability of an event.
Use the following format to find a z-score: z = X - μ / σ.
To be able to compare data distributions between them, we’d calculate the reduced centred variable:
To be able to compare data distributions between them, we’d calculate the reduced centred variable:
To be able to compare distributions of data between them, we calculate the reduced centered variable: z = (5.5 – 4.5) / 1.3 = 0.77
