Given a raw value of 20, a mean of 30 and a standard deviation of 10. what is the value of the z-score?

Question: Given a raw value of 20, a mean of 30 and a standard deviation of 10. what is the value of the z-score?

To find the z-score, we use the formula:

z = (x - μ) / σ

Where:

x = the raw value

μ = the mean

σ = the standard deviation

Substituting the given values, we get:

z = (20 - 30) / 10

z = -1

Therefore, the value of the z-score is -1.
