摘要: One of the most important problems with which mathematical statistician is faced that bringing his theoretical structures into some degree correspondence situations practical experience. This no doubt hardest when samples are small, for here he will often be two difficulties. In first place populations may not completely stable; sam-ple drawn a random one, but owing to difficulties in control or changing time factor cannot sure it quite same population concerned further work And then, even if stability population, generally impossible him obtain any certain estimate its exact form. For purposes inference calculate from sample one more statistical measures, difficulty make hesitate lay too much stress on value figures found entering probability table, while second wonder whether there after all appropriate table existence.
