Tatizo la Linganisho Nyingi

Wakati wa kufanya vipimo vingi vya takwimu, uwezekano wa kupata angalau moja ya matokeo ya uongo chanya kwa bahati huongezeka kwa idadi ya vipimo. Tatizo la linganisho nyingi (pia huitwa tatizo la wingi) hutokea kwa sababu ukifanya vipimo 100 vya dhahania kwa α = 0.05, unatarajia matokeo ya uongo chanya ~5 kwa bahati tu, hata kama dhahania zote sifuri ni za kweli. Njia za kusahihisha—Bonferroni, kiwango cha makosa cha ugunduzi wa uongo cha Benjamini-Hochberg (FDR), na zingine—hurekebisha kiwango cha umuhimu au maadili ya p ili kudhibiti viwango vya makosa. Dhana hii ni muhimu kwa uadilifu wa utafiti na ina athari kubwa kwa sayansi ya uchunguzi.
