How many standard deviations below the mean is 3 if it has z=-1.75?


A z score of -1.75  means that 3 is 1.75 below the mean.   z = -1.75

For example, the z-score value corresponding to each of the following locations in a distribution.

Below the mean by 3 standard deviations.     z = -3.00

Above the mean by 1/4 standard deviations.   z = 0.25

Below the mean by 2.50 standard deviations.   z =  -2.50
