2 Marks Questions:

1. Factorial Design is an experimental design where multiple factors are simultaneously varied to observe their effects on the response variable. (Definition of Factorial Design)
2. The advantage of using factorial design in experiments is its ability to efficiently analyze the main effects of factors as well as their interactions. (Advantage of Factorial Design)
3. Two compartment design divides experimental units into two distinct groups or compartments, allowing for separate treatments or conditions to be applied to each group. (Concept of Two Compartment Design)
4. Three compartment design extends the concept of two compartment design by dividing experimental units into three distinct groups or compartments, enabling more complex experimental setups and comparisons. (Description of Three Compartment Design)
5. Response Surface Methodology (RSM) is significant in experimental design as it provides a systematic approach for optimizing response variables influenced by multiple factors, leading to improved process efficiency and product quality. (Significance of Response Surface Methodology)

5 Marks Questions:

1. Central Composite Design in Response Surface Methodology involves a set of experimental runs arranged in a way to fit a second-order polynomial model, enabling the study of both linear and quadratic effects.
2. Historical Design approach in experiments utilizes existing data or historical information to inform the design and analysis of current experiments.
3. Optimization Techniques in experimental design commonly include methods such as gradient-based optimization, genetic algorithms, and simulated annealing to find the optimal conditions for a response variable.

10 Marks Questions:

1. Two factorial design involves two factors at two levels each, allowing the investigation of main effects, interaction effects, and higher-order effects, while three factorial design extends this concept to three factors. These designs are widely used in experiments for their ability to efficiently explore multiple factors and interactions.
2. Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to optimize response variables influenced by multiple factors. It involves the construction and analysis of response surfaces, often using designs like Central Composite Design, to find the optimal conditions for a process.
