- Uchambuzi wa Uchanganuzi
- pia inajulikana kama ANOVA, ni njia ya kupima kama au njia ya watu watatu au zaidi ni sawa. Njia hiyo inatumika ikiwa:
- Takwimu za mtihani kwa uchambuzi wa ugomvi ni\(F\) -uwiano.
- Njia moja ANOVA
- njia ya kupima ikiwa njia za watu watatu au zaidi ni sawa; njia hiyo inatumika ikiwa:
- Takwimu za mtihani kwa uchambuzi wa ugomvi ni\(F\) -uwiano.
- Uchanganuzi
- maana ya upungufu wa mraba kutoka kwa maana; mraba wa kupotoka kwa kawaida. Kwa seti ya data, kupotoka inaweza kuwakilishwa kama\(x – \overline{x}\) wapi\(x\) thamani ya data na\(\overline{x}\) ni sampuli maana. Tofauti ya sampuli ni sawa na jumla ya mraba wa upungufu uliogawanywa na tofauti ya ukubwa wa sampuli na moja.
