Computer Assignment #6

For this assignment:

You are expected to do your own work. You may seek help from others to learn how to carry out a procedure, but you are to do all aspects of the assignment yourself Therefore you should work through the complete assignment seeking help as necessary. If you do so without help- great. However if you have had help along the way with any aspect of a major component of the assignment (the major components are underlined on this assignment handout), then you should repeat the work on that component from beginning to end on your own. The work you turn in should represent your independent working of the assignment. In addition, the typed answers to questions that you submit are to be in your own words. The cover sheets that you sign will attest to the fact that you have adhered to these rules.

For this assignment:

- Define the variables:

0 use the column heads in the data section of this handout for the variable names

- each variable is numeric; make the width appropriate to the values for the variable (all are whole numbers and should have decimal =0 )

- label each variable (subject= "subject number"; diet = " diet condition"; score = "score (weight loss)"

- value labels are necessary for diet (1="diet A" ; 2=" diet B" ; 3= "diet C")

- make column width equal to 8

- select appropriate scale for each variable

- Enter data - enter the data and check the entered data carefully

- Analyze data:

0 Use Explore (Analyze > Descriptive Statistics > Explore) to get descriptives for score separately for each diet condition (A, B, and C) - Note: Dependent is score and Factor is diet.

- On "display" click "both". On "Plots" deselect stem-and-leaf but keep boxplots with" factor levels together". Click "Continue" and then "OK"

- Run a One-Way ANOVA (Analyze >Compare Means > One-W ay ANOVA) on score to determine if the three conditions significantly differ. For " Post Hoc" select Tukey (just plain Tukey); click "Continue" and then use "Options" to select Homogeneity of variance test; click "Continue" and then "OK".

- Print

- The output of the Explore procedure (including boxplots)

- Output of the ANOVA (including the Tukey Test and the test for Homogeneity of variance)

- Note: edit your output so that you print only the items called for (1-2)- and those should appear only once. Eliminate all trash. If necessary, print in landscape mode.

- Answer the following in writing (answers must be typed):

- Write a brief discussion of the appropriateness of these data for ANOVA (think normality assumption, level of measurement, and homogeneity of variance)

- Concerning the ANOVA: What is the value of \(F\) ? What is the p-value associated with this \(F\) ? Is \(F\) significant?

- Write an interpretation of the results of the ANOVA and the Tukey test and describe the implications for the study.
