摘要：The paper provides data on the dependence of the sample indicators of the arithmetic mean, variance, asymmetry and excess of the length of the needles of European spruce (Picea rubra) and European larch (Larix decidua), the average length of a pair of needles of Scots pine (Pinus sylvestris) and Calabrian pine (Pinus brutia). The sizes of samples have been determined, which make it possible to obtain the values of the estimates of sample indicators that have stabilized around their general values. The data on the difference between the law of distribution of the length of the needles of coniferous plants from the normal one are confirmed. The possibility of using graphs of the dependence of sample indicators on sample sizes for the examination of scientific data is discussed.
