An extensive set of interlaboratory root bioassay data was unified using centroids of individual tests as scalers. It is shown that the dose response obeys a first order differential equation with the constant of the equation related to the sensitivity of the dose response relationship evaluated in the central portion of the unified curve. The solution to the equation approximates the data rather well, making it suitable for prediction. A wide range of applications of the results demonstrate the utility of the approach and its potential for use in other bioassay work.
