On Comparison of Morphometrical Data Received «by Different Hands» and Morphometrical Indices Calculation

R. V. Novitsky, S. G. Krasovskii


On the basis of morphometrical data that are received by beginners as well as by experienced researchers studying anurans, the main errors of measured parameters and mistakes in morphometrical indices calculating are discussed. The influence of the probable errors of a measurement on the magnitude of the error in calculating morphometrical indices is analyzed. There are given recommendations to calculate correctly the averages of morphometrical indices and the mean error of a morphometrical index.
