If the difference between result and mean is 6 and the SD is 2, what is the Z-score?

Explanation:
Z-score tells how many standard deviations a value is from the mean. Compute it as Z = (X − μ) / σ. Here the difference from the mean is 6, and the standard deviation is 2, so Z = 6 / 2 = 3.0. This means the result lies three standard deviations above the mean.
