I performed a test where 24 subjects performed 3 trials with 4 conditions. So each person has three results of "best" conditions, and I have a total of 72 "best" conditions. I did a chi square goodness of fit test using all 72 trial results but realized I violated the assumption that all data come from independent sources. Are there any other tests that allow me to use all 72 trials, or can I only perform the chi square GoF test on the results of a single trial (for example, trial 3 with n=24)?
The "best" measurement refers to task time, but each user did not perform the same task so I can't do a parametric Anova. I want to be able to perform a statistical analysis of the best performing condition across all subjects, so I'm looking at frequency of best condition as opposed to using the time measurement. For example: the frequecies of best condition are as follows (for all 72 trials) condition 1:28, condition 2:16, condition 3:17, condition 4: 11 the chi square test shows significant difference when I compare all conditions, and also when I compare condition 1 to all three of the other conditions combined. Any help is greatly appreciated. -Joe [EMAIL PROTECTED] . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
