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 transforming data from multiple distributions to the standard normal distribution?
• What is the relationship between z scores and percentages?
• Give an example of a variable likely to be normally distributed in the population and explain how z scores pertaining to that variable would be useful in a real-life situation.
