Here we have scores of the students and we need to find the Z score for the data.

For mean, we will use the AVERAGE function and For Standard deviation, STDEV.P function.

Use the formula:

=STANDARDIZE(A2, AVERAGE(A2:A12), STDEV.P(A2:A12))

A2 : value to be normalised
AVERAGE(A2:A12) : mean of the data
STDEV.P(A2:A12) : Standard deviation of the data
