Příspěvek k nápravě opomíjení významu síly testů ve studiích z experimentální medicíny

Práce poskytuje základní informaci o tom, co z hlediska správného využívání matematické statistiky v medicíně se rozumí pod pojmem „statistická analýza síly testu“. Jsou zde podrobně popsána pravidla statistického rozhodování. Dále práce obsahuje ukázku aplikace analýzy síly testu na nepárový t-test.

Klíčová slova:
