Psych 625 Practice Week 2

...University of Phoenix Material Time to Practice – Week Two Complete Parts A, B, and C below. Part A 1. Why is a z score a standard score? Why can standard scores be used to compare scores from different distributions? (2 points) A z score is considered a standard score because the standard score is the number of standard deviations and observation or datum is above the mean. Standard scores are called z scores because the normal distribution is known as Z distributions. A z score is considered a standard score because it is based on the degree of variability within its distribution. Standard scores across different distributions measure in the same fashion. A z score is the result of dividing the amount that a raw score differs from the mean of the distribution by the standard deviation. So, scores below the mean will have negative z scores, and scores above the mean will have positive z scores. Positive z scores always fall to the right of the mean, and negative always fall to the left (Salkind, 2014). 2. For the following set of scores, fill in the cells. The mean is 74.13 and the standard deviation is 9.98. (2 points) |Raw score |Z score | |68.0 |-0.61 | |58.2 |–1.6 | |82.0 |0.79 | |92.1 |1.8 | |69.0 |-0.51 | |69.1 |–0.5 | |85.0 |1.09 | |91.9 |1.7 ...
