Question

Using the formula below, calculate the z-score for the listed data points. z-score: zx = x − μ σz1= z5=z6.5=

Answer 1

z1 =  -1.95

z5 =  0.05

z6.5 = 0.8

Answer 2

The value of the z score is 1 for a mean of 2 and standard deviation of 1

What is Z score?

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ)/σ

Where x is the raw score, μ is the mean and σ is the standard deviation.

Let us assume that μ = 2, σ = 1, hence for x = 3:

z = (3 - 2) / 1 = 1

The value of the z score is 1 for a mean of 2 and standard deviation of 1
