The Z Score is a statistical measure used to compare a given data point to the average of a group of data points. It is calculated by subtracting the average of the group from the given data point, and then dividing the result by the standard deviation of the group. The Z Score can be used to determine how far away from the average a given data point is.
A Z Score Calculator is a tool used to calculate the standard score (also known as the z-score) of a given data point. The z-score is a measure of how many standard deviations a data point is from the mean of a given data set. It is used to compare the relative position of a data point within a data set.
To calculate a Z Score, you need to subtract the population mean from an individual’s raw score and then divide that number by the population standard deviation. The formula is: Z Score = (Individual Score – Population Mean) / Population Standard Deviation.
