Part 1:

Use the IQ variable, choose 10 scores, in the Howell Excel Data Set and transform the x values into z-scores using the = 90 with = 17. Then put all information in a table using the "

You need to compare the IQ, the same 10 scores, to the national average of = 100 with = 15 for the students in the math class. Add another column to your chart, using the "

Part 2:

Then, in

Explain the reasons why transforming x values into z-scores is useful by using the example of the problem you solved in Part 1. Your explanation should include:

Why knowing the z-scores for IQ helps you to understand the standard normal distribution of these scores for the math class.

How z-scores can help researchers use the data from a sample to make inferences about a population.

How converting the IQ scores (x-score) to the more familiar metric IQ scores (z-scores) in the second column can be helpful for the students in the math class.
