This document discusses how to calculate standard scores like the Z-score, t-score, and percentile in Minitab. It defines the Z-score as having a mean of 0 and standard deviation of 1, and the t-score as being calculated from the Z-score using the formula T = 50 + 10Z, giving it a mean of 50 and standard deviation of 10. It also defines the percentile as the percentage of scores in a data set that fall below a particular score. The document provides information and instructions on calculating each of these standard scores in Minitab.

8. Calculate t Score
▹ Definition. T scores (or T-scores) are
an example of standardized scores,
where the mean is equal to 50 and the
standard deviation is equal to 10. They
are a linear transformation of Z-scores,
which have mean 0 and standard
deviation 1; a T score can be obtained
from a Z-score by the formula
▹ T = 50 + 10Z.

17. Calculate Percentile Score
▹ A percentile is a term used in statistics to express
how a score compares to other scores in the same
set. While there is technically no standard definition
of percentile, it's typically communicated as the
percentage of values that fall below a particular value
in a set of data scores.
