Raw
data from previous example
The
following displays z-scores automatically created by software when conducting a
descriptive analysis (an option on most software). Software
calculates the mean and standard deviation for the sample data and then calculates the
z-score for each observation and outputs the result to the data file thereby creating a
new variable (in this case Z-Age).
