You would like to measure the effect of fast food on performance. You administer one group of workers fast food for one month. You administer a second group of workers half fast food and half non fast food for one month. You administer a third group of workers non fast food for one month. Each worker participates in all conditions of the experiment as each condition is separated by one month of time. After each month, you measure how productive workers are by counting how many widgets they have produced during that month. The following are the results.  See the number of widgets produced by each worker in each condition.

 Condition 1: Fast Food Condition 2: Half Fast Food and Half Non Fast Food Condition 3: Non Fast Food Worker 1 = 234 widgets Worker 2 = 345 widgets Worker 3 = 243 widgets Worker 4 = 221 widgets Worker 5 = 226 widgets Worker 6 = 345 widgets Worker 7 = 267 widgets Worker 1 = 210 widgets Worker 2 = 320 widgets Worker 3 = 230 widgets Worker 4 = 227 widgets Worker 5 = 230 widgets Worker 6 = 346 widgets Worker 7 = 268 widgets Worker 1 = 1000 widgets Worker 2 = 1245 widgets Worker 3 = 1340 widgets Worker 4 = 1100 widgets Worker 5 = 900 widgets Worker 6 = 1500 widgets Worker 7 = 1245 widgets

1. Conduct a 1-Way Within Subjects ANOVA

2. Based on your experimental design, report the type of test used and what it was used to test by filling in the blanks of the following sentence.

“A _________________________ was conducted to compare ______________ in

______________, _______________ and _______________ conditions.”

3. Based on your SPSS output and the design of this experiment, fill in the blanks in the following sentence and circle significant or not significant.

“There was a significant (not a significant) effect of _______________, Wilks’ Lambda

= ______, F  (_______,_______) = _______, p = _______.  Post hoc comparisons using

the____________________ test indicated that _________________________________

_______________________________________________________________________

_______________________________________________________________________”

4. Write a sentence that states what your results mean in terms of your experiment – in words that an inexperienced scientific reader could understand.
