Your Name Questions Scenario: Suppose you have a sample of 65 juveniles arrested by the local police department over the past six months. You have a distribution of scores that represent the number of prior offenses committed by this sample. The metric of measurement is number of arrests. 1. What is the level of measurement? Mean and standard deviation: For this sample, the mean number of prior arrests is 4.8 and the standard deviation is 3.25. For an analysis, a z-score would be calculated for each raw score. Refer to your textbook for how to calculate a z-score. 2. What is the z-score for a raw score of 3? 3. What is the z-score
