Explain why an analysis of variance is appropriate for


Assignment

Hotdogs are available with different meat compositions such as poultry, beef, pork, or a mixture of these (called ‘meat' here). For this project, you will investigate whether there are differences in the mean sodium content of poultry, beef, and meat hotdogs. The data are available in the file ‘hot dogs.txt".

1. Explain why an Analysis of Variance is appropriate for these data.

2. Create appropriate graphical summaries of the data. Use these summaries to

i. Draw preliminary conclusions about the data - justify your conclusions.

ii. Check the assumptions that underlie ANOVA.

3. Conduct ANOVA to compare the mean sodium content of the different meat content hotdogs.

Report instructions:

The report must be typed and double-spaced; no more than 3 pages including graphics. Include all figures, summaries and computer output used in your analysis.

The write-up will include the following (labeled) sections:

I. Problem Statement
II. Methods
III. Conclusions
IV. Discussion

I. Problem Statement:

In this section, the author will describe the question(s) being addressed in the analysis and any relevant background that is helpful to understanding the question.

II. Methods

In this section, the author will describe the work that he/she has done. This should include a description of the methods used, the rationale behind using the chosen methods, comparison of information that can be obtained from the different methods, and computer output.

III. Conclusions: In this section, the author will describe his/her conclusions and the justification for these conclusions from the work done.

IV. Discussion: In this section, the author will discuss the limitations of his/her analysis, describe additional questions that would be of interest to investigate with the data, and offer any final insights into the question under consideration.
