The document discusses the importance of converting raw scores to standardized z-scores. It provides the formula for calculating a z-score and explains that a z-score indicates how many standard deviations a score is from the mean. Several examples are given of calculating z-scores based on different hypothetical scores and population means and standard deviations. The key benefits of z-scores are that they allow for comparison of scores from different distributions and indicate whether a score is above, below, or at the average.
