Syntaktyka funkcji<\/h2>\n

Dla Excela funkcja DSTDEV jest zdefiniowana w nast\u0119puj\u0105cy spos\u00f3b:<\/p>\n

=DSTDEV(baza_danych; pole; kryteria)<\/code><\/pre>\n
    \n
  • baza_danych<\/strong> \u2013 zakres kom\u00f3rek zawieraj\u0105cy dane w\u0142\u0105czaj\u0105c w to nag\u0142\u00f3wki kolumn.<\/li>\n
  • pole<\/strong> \u2013 numer kolumny (liczony od 1) lub nazwa kolumny w cudzys\u0142owach, kt\u00f3ra ma by\u0107 poddana analizie.<\/li>\n
  • kryteria<\/strong> \u2013 zakres kom\u00f3rek definiuj\u0105cych, kt\u00f3re dane z bazy maj\u0105 by\u0107 uwzgl\u0119dnione.<\/li>\n<\/ul>\n
    W Google Sheets funkcja BD.ODCH.STANDARD przyjmuje podobn\u0105 syntaktyk\u0119:<\/p>\n
    =BD.ODCH.STANDARD(baza_danych, pole, kryteria)<\/code><\/pre>\n
    Zastosowania praktyczne<\/h2>\n
    Oto kilka przyk\u0142ad\u00f3w zastosowania funkcji DSTDEV i BD.ODCH.STANDARD w realnych zadaniach.<\/p>\n
    Przyk\u0142ad 1: Obliczanie standardowego odchylenia sprzeda\u017cy<\/h2>\n
    Za\u0142\u00f3\u017cmy, \u017ce dysponujesz baz\u0105 danych z wynikami sprzeda\u017cy po regionach na przestrzeni miesi\u0119cy. Je\u015bli chcesz obliczy\u0107 standardowe odchylenie sprzeda\u017cy dla regionu „Wsch\u00f3d”, twoja baza danych mo\u017ce wygl\u0105da\u0107 tak:<\/p>\n\n\n\n\n
    Miesi\u0105c<\/td>\nRegion<\/td>\nSprzeda\u017c<\/td>\n<\/tr>\n
    Stycze\u0144<\/td>\nWsch\u00f3d<\/td>\n25000<\/td>\n<\/tr>\n
    Stycze\u0144<\/td>\nP\u00f3\u0142noc<\/td>\n45000<\/td>\n<\/tr>\n
      <\/table>\n
    Je\u015bli zakres z danymi to A1:C10, a zakres z kryteriami to F1:F2 (F1 = „Region”, F2 = „Wsch\u00f3d”), stosujemy wz\u00f3r:<\/p>\n
    =DSTDEV(A1:C10, 3, F1:F2)<\/code><\/pre>\n
    Przyk\u0142ad 2: Analiza wynik\u00f3w testowych uczni\u00f3w<\/h2>\n
    Posiadasz baz\u0119 danych z wynikami test\u00f3w uczni\u00f3w. Aby okre\u015bli\u0107 standardowe odchylenie wynik\u00f3w dla klasy 3A, struktura twojej bazy mo\u017ce wygl\u0105da\u0107 tak:<\/p>\n\n\n\n\n
    Imi\u0119<\/td>\nKlasa<\/td>\nWynik<\/td>\n<\/tr>\n
    Ania<\/td>\n3A<\/td>\n85<\/td>\n<\/tr>\n
    Kamil<\/td>\n2B<\/td>\n92<\/td>\n<\/tr>\n
      <\/table>\n
    Przy za\u0142o\u017ceniu, \u017ce dane s\u0105 w zakresie A1:C20, a kryteria w F1:F2 (F1 = „Klasa”, F2 = „3A”), wz\u00f3r b\u0119dzie wygl\u0105da\u0142 nast\u0119puj\u0105co:<\/p>\n
    =DSTDEV(A1:C20, \"Wynik\", F1:F2)<\/code><\/pre>\n
    Funkcje DSTDEV i BD.ODCH.STANDARD s\u0105 nieocenionymi narz\u0119dziami do obliczania standardowego odchylenia dla wybranej podgrupy danych, co ma kluczowe znaczenie przy analizach statystycznych i wspiera podejmowanie decyzji w r\u00f3\u017cnych dziedzinach, zar\u00f3wno w \u015bwiecie biznesu, jak i edukacji.<\/p>\n","protected":false},"excerpt":{"rendered":"
