Latar belakang dikembangkan metoda ini karena ingin dilakukan testing terhadap rata-rata populasi yg mengalami “perlakuan” yg berbeda-beda. Pertanyaannya : apakah perbedaan rata-rata antara berbagai grup yg mengalami perlakuan berbeda tsb signifikan atau tidak. Asumsi untuk ujia ANOVA adalah: Populasi semuanya normal Standard deviasi populasi sama Populasi independen MIsal ada 4 grup A,B,C dan D dengan rata-rata sampel xA, xB, xC dan xD. Ingin diketahui apakah rata-rata populasi yg terkait dengan sampel tsb sama? Tentu saja kita bisa melakukan uji statistik bagi tiap sepasang mean, misal μA=μB lalu μA=μC dst. Semuanya ada 6 pasangan yg mungkin, jadi ada 6 uji yg harus dilakukan. Untuk masing-masing dilakukan test-t
