title: [Use of the straightened diagram method in morphologic studies].
abstract: A possibility is demonstrated to use a technical method of strahtened diagrams in order to check hypotheses of normal distribution for treating experimental morphological data. The method is a graphic interpretation of experimental values in the coordinate system: measured values (abscissa) and accumulated frequences (ordinate). In the case of the law on normal distribution, the experimental dots are distributed closely enough to the straight line drawn along the average arithmetic parameters of observation and their mean square deflection. Confidence intervals plotted on the diagram accurately enough serv as a criterion for the experimental dots proximity to the straight line. The order of calculation to build the straightened diagram for a large (several hundreds) number of values is represented. An example is given when the method is not applied.
