For this assignment, identify the appropriate application of standardized scores to reflect on their benefits and to interpret how test scores and measures are commonly presented.

Review Chapter 3 of your course text, which introduces probability and the standard normal distribution.  Examine the assumptions and limitations presented in these topics and then consider and discuss the following questions:

• When comparing data from different distributions, what is the benefit of transforming data from these distributions to conform to the standard distribution? 
• What role do z-scores play in this transformation of data from multiple distributions to the standard normal distribution? 
• What is the relationship between z-scores and percentages? 
• In your opinion, does one do a better job of representing the proportion of the area under the standard curve?  Give an example that illustrates your answer.
