Upimaji wa Hipothesi sifuri

Upimaji wa Umuhimu wa Hipothesi sifuri (NHST) ndio mfumo mkuu wa takwimu katika utafiti wa majaribio. Hipothesi sifuri (H₀) huwakilisha dhana ya msingi—kawaida 'hakuna athari' au 'hakuna tofauti'—wakati hipothesi mbadala (H₁) huwakilisha dai linalojaribiwa. Jaribio huhesabu uwezekano wa kuona data ikizingatiwa kuwa H₀ ni kweli (p-value); ikiwa p ni ndogo sana, H₀ inakataliwa kwa ajili ya H₁. Iliyoundwa na Ronald Fisher na kupanuliwa na Neyman na Pearson mapema karne ya 20, NHST ni msingi wa utafiti wa uthibitisho lakini imekosolewa sana kwa matumizi mabaya na tafsiri isiyo sahihi.
