Web3-way Anova provides analysis for 3 factors. I don’t know what you mean by 2-way 2^k factor analysis. A 2^k design is a k-way Anova where each factor has 2 levels. Thus, 2^3 design is a 3-way Anova where each factor has exactly two levels. Charles WebThe experimental design used was a Factorial Random Block Design which consisted of two factors and was repeated 3 times. The first factor is rice husk biochar (A) consisting of 3 levels, namely 0 g/paralon, 4000 g/paralon and 8000 g/paralon and the second petroganic factor (P) consists of 3 levels, namely 0 g/tan, 1 g/tan and 2 g/tan.
