Abstract

In Reply.  —The study was designed for the purpose of ascertaining the relationship of a single variable, the qualifications of medical technologists, and the quality of laboratory results. From Dr Peddecord's comments it seems that he is accustomed to using parametric statistical techniques such as multiple regression. Multiple regression makes assumptions about the sample distributions. If these assumptions are violated, then the results must be suspect. In this study, to avoid any distribution peculiarities in the sample(s), nonparametric statistics were used to analyze the data. A Spearman rs correlation of.34 (P<.001) was reported. It was not the intent of the study to contend that ASCP-certified medical technologists are independent of other laboratory characteristics, but rather to confirm the predictable expectation that employing ASCP-certified medical technologists influences the quality of laboratory results.
