Problem 2

A researcher developed a novel instrument (Measure A) for measuring giftedness in young children. She wanted to compare the new measure to an established measure (Measure B). She gave both measures to a sample of 100 kids and got the following results: Use Excel and show work.

		Measure B
		Not Gifted	Gifted
Measure A	Not Gifted	79	1
Gifted	16	4

1. Interpret the numbers in the table. What does the 79 represent? What does the 16 represent?

1. Is a chi-squared test of association appropriate in this context? Why or why not?

1. Conduct an appropriate analysis of the research question.

1. Interpret the results of the test.

1. What proportion of students were labeled gifted by Measure A?

1. What are the odds of being labeled gifted by Measure A?

1. What proportion of students were labeled gifted by Measure B?

1. What are the odds of being labeled gifted by Measure B?

1. What is the odds ratio between Measure A and Measure B? Interpret.
