Question: One of the advantages to using ranks instead of interval or ratios scores is that ranks can reduce the effect of one extreme individual scores. The following data represents from an independent Measure study comparing two treatments. Notice that most subjects in treatment 1 have scores around 15. However there is one odd individual treatment in 2 with a scores of x=104. The extreme scores distorts the data so that an independent measure t test indicates no differences btwn treatments t(10)=0.0868, p> 0.05. When the scores are converted to ranks however, the extreme score is much less dramatic. Transform the score into ranks and use Mann Whitney test to evaluate the difference btwn test alpha with 0.05.
