For this discussion, 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
When comparing data from different distributions, what is the
benefit of transforming data from these distributions to conform to the
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.
