    Kazi katika vikundi juu ya matatizo haya. Unapaswa kujaribu kujibu maswali bila kutaja kitabu chako. Ikiwa unakabiliwa, jaribu kuuliza kikundi kingine kwa usaidizi.

    Mwanafunzi Kujifunza Matokeo

    • Mwanafunzi atafanya\(ANOVA\) mtihani rahisi wa njia moja unaohusisha vigezo vitatu.

    Kusanya Data

    Rekodi bei kwa kilo moja ya matunda nane, mboga nane, na mikate nane katika maduka makubwa ya eneo lako.

    Matunda Mboga Mikate

    Eleza jinsi unavyoweza kujaribu kukusanya data kwa nasibu.

    Kuchambua Data na Kufanya Mtihani wa Hypothesis

    1. Kokotoa yafuatayo:
      1. Matunda:
        1. \(\bar{x} =\)______
        2. \(s_{x} =\)______
        3. \(n =\)______
      2. Mboga:
        1. \(\bar{x} =\)______
        2. \(s_{x} =\)______
        3. \(n =\)______
      3. Mkate:
        1. \(\bar{x} =\)______
        2. \(s_{x} =\)______
        3. \(n =\)______
    2. Pata zifuatazo:
      1. \(df(\text{num}) =\)______
      2. \(df(\text{denom}) =\)______
    3. Weka usambazaji wa takriban kwa mtihani.
    4. Takwimu za mtihani:\(F =\) ______
    5. Mchoro grafu ya hali hii. WAZI, studio na kuongeza mhimili usawa na kivuli kanda (s) sambamba na\(p\text{-value}\).
    6. \(p\text{-value} =\)______
    7. Mtihani katika\(\alpha = 0.05\). Hali uamuzi wako na hitimisho.
      1. Suluhisho: Kwa nini ulifanya uamuzi huu?
      2. Hitimisho (kuandika sentensi kamili).
      3. Kulingana na matokeo ya utafiti wako, kuna haja ya kuchunguza yoyote ya bei ya makundi ya chakula '? Kwa nini au kwa nini?
