A Z score can be positive or negative, with a higher value indicating a greater deviation from the mean. A Z score of 0 indicates that the data point is equal to the mean, while a Z score of 1 or 2 indicates that the data point is one or two standard deviations away from the mean.

In simple terms, a Z score represents the number of standard deviations an observation is from the mean. It's a measure of how unusual a data point is in relation to the rest of the data. To calculate a Z score, you need to know the mean and standard deviation of the data set. Once you have these values, you can use a Z score formula to determine the score. A Z score can be positive or negative, with a higher value indicating a greater deviation from the mean. By understanding Z scores, you can determine whether a data point is statistically significant or not.

How Z Scores Work

Misconception: Z scores are only used in academic research.
