Go to the online library and find a recent (no older than 3 years) article reporting the results of a nursing or health research study in which a multivariate analysis of variance analysis is used (try using health research and MANOVA or multivariate analysis as search terms).

Post the reference using APA format at the top of your response and then provide a BRIEF one paragraph summary of the study.

Identify the null hypothesis and alternative hypotheses (you will need to write the null in your own words as this is not provided in most research reports).

State the type of ANOVA that was used (Two-way ANOVA, MANOVA)

Address the type of data required and whether assumptions of the test were met.

In order to do this, you will need to state:

-What was the Dependent Variable (DV) and at what level was it measured -What was the Independent Variable (IV) and at what level it was measured

You will then compare this to the type of data required and whether assumptions of the test were met.

* Article have to be related to nursing*  USE Research data base.

PROBLEM 4

Classified ads in the Ithaca Journal offered several used Toyota Corollas for sale. Listed 

below are the ages of the cars and the advertised prices. 

Age (yr) Price Advertised ($)

1 13,990

1 13,495

3 12,999

4   9,500

4 10,495

5  8,995

5  9,495

6  6,999

7  6,950

7  7,850

8  6,999

8  5,995

10  4,950

10  4,495

13  2,850

 

(a) Report the linear correlation coefficient value and comment on the form, the 

direction, and strength of association between the age of a car and the advertised 

price.  

(b) Report the equation of the least-squares regression line. Interpret the coefficients. 

(c) Report and interpret the value of the coefficient of determination. 

(d) Carry out a T-test about correlation ( H1p≠0). Use a 5% level of significance.  

 

EXPECTATIONS

 Draw graphs and charts when appropriate and necessary to demonstrate your 

reasoning! Label all graphs and charts! 

Display formulas. Write complete sentences to summarize your conclusions. 

If use any table values, clearly state which tables you used (e.g. Table A-2, etc.).  

You may attach your excel output when appropriate or necessary (e.g. a scatterplot, 

etc.) 

 

HYPOTHESIS TESTING QUESTIONS

Your work for all statistical hypothesis testing questions should include the following

1. Established Ho and Ha.

2. Summary statistics (either computed or given in the problem)

3. The name of the test (e.g. 2sampleTtest or T-test about correlation, etc.)

4. A formula to compute a test statistic (e.g. 1Prop-Z test statistic, etc.)

5. A p-value of the test and/or a critical value from a statistical table.

6. Clearly state the decision rule you use the reach a conclusion. (You may have to 

sketch a graph to show rejection regions.) Do you “Reject Ho” or do you “Fail to 

Reject Ho”?

7. State your conclusion in plain language. Use complete sentences.
