Krok 1: Wprowad\u017a dane<\/span><\/strong><\/span><\/h3>\n

Za\u0142\u00f3\u017cmy, \u017ce kierownik restauracji chce zmierzy\u0107 og\u00f3ln\u0105 satysfakcj\u0119 klienta. Postanawia wys\u0142a\u0107 ankiet\u0119 do 10 klient\u00f3w, kt\u00f3rzy b\u0119d\u0105 mogli oceni\u0107 restauracj\u0119 w skali od 1 do 3 dla r\u00f3\u017cnych kategorii.<\/span><\/p>\n

Zacznijmy od wprowadzenia danych zawieraj\u0105cych odpowiedzi na ankiet\u0119 dla ka\u017cdego z 10 klient\u00f3w:<\/span> <\/p>\n

Krok 2: Wykonaj dwukierunkow\u0105 ANOVA bez replikacji<\/strong><\/span><\/h3>\n

Nast\u0119pnie przeprowadzimy dwukierunkow\u0105 ANOVA bez replikacji.<\/span><\/p>\n

Aby to zrobi\u0107, kliknij kart\u0119 Dane<\/strong> na g\u00f3rnej wst\u0105\u017cce, a nast\u0119pnie kliknij opcj\u0119 Analiza danych<\/strong> w grupie Analiza<\/b> :<\/span> <\/p>\n

Je\u015bli ta opcja nie jest dost\u0119pna, nale\u017cy najpierw za\u0142adowa\u0107 pakiet Analysis ToolPak<\/a> .<\/span><\/p>\n

W wy\u015bwietlonym menu rozwijanym kliknij Anova: Two-Factor Without Replication<\/strong> , a nast\u0119pnie kliknij OK<\/strong> . W nowym oknie, kt\u00f3re si\u0119 pojawi, podaj nast\u0119puj\u0105ce informacje, a nast\u0119pnie kliknij OK<\/strong> :<\/span> <\/p>\n

Pojawi\u0105 si\u0119 nast\u0119puj\u0105ce wyniki:<\/span> <\/p>\n
