Question

10. Dr. Antonio believes that you can predict people’s choice of mate from their personal inventory of characteristics (PIC; measured 1-15). He administers the PIC to 100 students on campus and has those students rate the likelihood of dating a group of 10 co-eds (mate choice is measured on a 1-100 scale; 10 pts for each co-ed).

1. What are the researcher’s independent and dependent variables?

a. Independent:

b. Dependent:

2. What are the null and alternative hypotheses (use the appropriate symbols not words)?

a. H0:

b. H1:

3. What is the appropriate test for the researcher to use?

4. Why is that statistic appropriate?

If applicable to the specific test:

5. What are the test’s assumptions?

6. What are the test’s df?

7. What is the appropriate critical value?

8. If the research obtains a test statistic of ____ , would the researcher retain or reject H0?

9. Should the researcher do any follow up tests or make any graphs/charts?

10. Interpret the findings in APA style

Explanation / Answer

SOLUTION:-

1)

a.Independent=personal inventory of characteristics

b.Dependent= choice of mate

2)

Hypothesis

Null hypothesis H0 : personal characteristics and people’s choice are independent

Alternative Hypothesis H1 : personal characteristics and people’s choice are dependent

3)

The appropriate test for the researcher to use is Chi Square test since it is a qualitative data.

5)

Test assmuption are a) each frequency must be greater than 5 and b) total sample size must be greater than 50

6)

df = n-1 = 10 - 1 = 9

7)

appropriate critical value is 123.22

8)

If the calculated value of the test statistic is less than the critical value then the decision is reject to null hypothesis. Otherwise fail to reject the null hypothesis.
