Z Scores Are Useful Because They

question 56

Multiple Choice

z scores are useful because they:

• A) allow us to convert raw scores to mean scores, compare scores from different samples, and transform populations into samples.
• B) transform linear scores into nonlinear scores, convert nonlinear scores back into linear scores, and allow us to obtain comparisons between nonlinear and linear scores.
• C) give us an understanding of where a score falls in relation to the mean of its underlying population, allow comparisons to be made between scores from different distributions, and permit the transformation of z scores into percentiles.
• D) reduce the probability of Type I and Type II errors, allow us to compare raw scores with standard scores, and permit the transformation of raw scores into percentiles.
