The calculator tool used to calculate the Z score of the given statistical values is called a Z score calculator. Z score is called as the standard score which can be calculated for each value in a set of data for the given mean and standard derivation of a sample.
Example 1: Calculate the Z score for the given statistics of population mean 3,
population standard deviation 0.25 and value 4.5?
In, this problem the Z score is to be calculated for the value 4.5
Given the mean of the population = 3
The standard deviation = 0.25
Z score of the given data can be calculated as shown below:
Z score = Value of the data - Mean of the given data / Standard deviation
Z Score = 4.5 - 3 / 0.25 = 6.0
Example 2: Calculate the Z score for the given statistics with population mean 24,
population standard deviation 7.5 and value 8.2?
In, this problem the Z score is to be calculated for the value 8.2
Given the mean of the population = 24
The given standard deviation= 7.5
Z score = Value of the data - Mean of the given data / Standard deviation
Therefore, Z Score = 8.2 - 24 / 7.5 = -2.1
