Abstract
It is notoriously difficult to do experimental diving scientifically. The advent of more sensitive indicators of decompression stress, i.e. Doppler ultrasonic bubble detectors has provided a richer source of data for analysis. Originally it was hoped that these could prove to be fool-proof diagnostic tools for predicting DCS. It is now understood that they are not, and a better appreciation of how to use these instruments has emerged. In addition, it is necessary to improve our understanding of how to analyze the data that they furnish. When the categorical nature of the data is realized and the assumptions underlying the normal statistical tests are examined, it is seen that only non-parametric tests can apply. This is not a great restriction, however, because there are many such tests allowing considerable scope for analysis.
