Scenario:

An instructor in a computer literacy course wanted to measure progress in learning to use a versatile word-processing program. His intention was to encourage students to use a variety of formatting commands available, particularly by using the macro-writing ability of the program. 

His plan was to give students 5 test sessions during which they would attempt to use the word-processing program to enter a document into the computer. He prepared five different documents, each differing in content but using the same number of formatting instructions. The five documents were arranged in five different orders that were properly counterbalanced. He selected five students who were approximately equally skilled in typing and computer experience. They were given the training manual to study one week before the experiment began, following which time they were given a series of five tests during which they attempted to enter a document into the computer within a one-hour time limit. The dependent variable consisted of the number of different formatting commands the student used in attempting to reproduce the document with the word-processing program.

Is there a significant difference in the number of formatting commands used across the five test conditions? Set alpha at .05.
