While Z scores are typically used with normal distributions, you can use them with non-normal distributions by transforming the data into a normal distribution. However, this is not always necessary and may not be the most effective approach.
For example, let's say you're analyzing a dataset of exam scores with a mean of 80 and a standard deviation of 10. If a student scored 90, their Z score would be (90 - 80) / 10 = 1.
