• EFFECT OF DETERGENTS ON CLOTH TYPES: A 2*2 FACTORIAL EXPERIMENT

Abstract

A full factorial experiment allows studying the effect of each factor on the response variable, as well as effect of interactions between factors. There is variation in only two factors – cloth types and detergent types and all other conditions are constant. The effects of different treatment combinations are checked. The findings give the exact idea about the suitability of combination of these factors for satisfactory result. The factor with its high level (+) and low level (-) shows presence or absence in treatment combination. The factors are noted as A and B in 2*2 factorial experiment with its corresponding levels a0 and a1, as well as b0 and b1, give four treatment combinations such as a0b0 as (1), a1b0 as a, a0b1 as b and a0b0 as ab.
