What is the definition of Completely Randomized Design?
Experimental units are assigned to treatments randomly. Each unit has an equal chance of being in any treatment group.
What is the definition of Blocking Design?
Experimental units are grouped into blocks based on a variable that might affect the response, then randomization occurs within each block.
What is the definition of Matched Pairs Design?
Similar units are paired up (or the same unit is used twice), and then treatments are randomly assigned within each pair.
What are the differences between Completely Randomized Design and Blocking Design?
Concept 1: Simple, easy to implement | Concept 2: Controls for known variables, reduces variability
What are the differences between Blocking Design and Matched Pairs Design?
Concept 1: Blocks based on a variable, randomizes within blocks | Concept 2: Pairs similar units, randomizes within pairs
Explain the concept of Completely Randomized Design.
Experimental units are assigned to treatments randomly, ensuring each unit has an equal chance of being in any treatment group.
Explain the concept of Blocking Design.
Experimental units are first grouped into blocks based on a variable, then treatments are randomized within each block to reduce variability.
Explain the concept of Matched Pairs Design.
Similar units are paired up, or the same unit is used twice, and then treatments are randomly assigned within each pair to minimize individual differences.
