Split Plot Design

The design in which the levels of one factor can be applied to large experimental units and the levels of other factors to the sub-units are known as “split plot design“. A split plot experiment is a blocked experiment in which blocks serve as experimental …

Layout of the Factorial Design: Two Factor $2^2$ (2024)

The layout of a factorial design is typically organized in a table format. Each row of the table represents an experimental run, while each column represents a factor or the response variable. The levels of factors are indicated by symbols such as + and – …

What is Factor Effects of $2^2$ Design (2024)

The smallest case of a $2^K$ factorial experiment is one in which 2 factors are of interest and each factor has two levels. This design is known as a $2^2$ factorial design. We are interested in Factor effects or Effects of Factors. The level of …

The Factorial Experiment advantages and disadvantages over One-Factor-at-a-time Experiment. Factorial Experiment Advantages Effect of changing factor $A = A_2 B_1 – A_1B_1$ Effect of changing factor $B = A_1B_2 – A _1 B_1$ Three treatment combinations are used for two effects for error estimation we …
