How Do Z Scores Work?
A Z score, also known as a standard score, is a measure of how many standard deviations an element is from the mean. It's calculated by subtracting the mean from the value and then dividing the result by the standard deviation. This gives a score that indicates how far away a value is from the average. For example, if a score is 2, it means that the value is 2 standard deviations above the mean. Z scores are often used to compare data from different groups or to identify outliers.
This topic is relevant for anyone who works with data, including:
Z scores can be interpreted in different ways depending on the context. A positive Z score indicates that the value is above the mean, while a negative Z score indicates that it's below the mean. A Z score of 0 means that the value is equal to the mean.

Yes, Z scores have some limitations. They assume a normal distribution, and if the data does not follow a normal distribution, Z scores may not be accurate. Additionally, Z scores do not take into account the magnitude of the differences, only the direction.
Z scores can be used with any type of data that has a normal distribution, such as heights, weights, or scores on a test. However, if the data does not have a normal distribution, Z scores may not be accurate.
