General
an independent variable that probably has an effect on the response, BUT we are NOT interested in that effect.
Randomized Complete Block Design
What is RCBD
An experimental design used to control two nuisance factors simultaneously.
What is a Latin Square Design?
Balanced Incomplete Block Design
An experimental design where all possible combinations of factor levels are tested.
What is a Full Factorial Design?
Dependent variables
blocking technique
In a Latin square design, each treatment appears exactly once in every row and once in every column.
How is the Latin square design arranged?
In a BIBD, this property ensures that every pair of treatments appears together in exactly the same number of blocks
What is the balanced property?
In a 2k factorial design, this symbol represents the number of factors.
What is k?
Independent variables
What are factors in DOE?
randomization
If there are t treatments in a Latin square design, this is the total number of experimental runs
What is t^2?
In a BIBD, this symbol represents the number of treatments included in each block.
What is k?
This type of effect measures how the impact of one factor changes depending on the level of another factor.
What is an interaction effect?
different conditions of the experiment
what are treatments?
In RCBD, all experimental runs inside this unit are randomly assigned.
What is a block?
This component of the model captures the unexplained variation due to random noise.
What is the random error?
In a Balanced Incomplete Block Design, this parameter represents the number of times each treatment appears across all blocks
What is r?
A linear combination of treatment means used to estimate effects in factorial experiments.
What is a contrast?
Extraneous factor is made to vary deliberately over as wide a range as necessary in such a way that the variability it causes can be measured and eliminated from the experimental error
The variability that RCBD tries to minimize by grouping similar experimental units.
What is within-block variability?
In Latin Square ANOVA, the total sum of squares is partitioned into row, column, treatment, and this remaining component.
What is the error sum of squares
This quantity measures the variation among treatments after removing the effect of blocks in a BIBD.
What is the Adjusted Treatment Sum of Squares?
The degrees of freedom for the interaction effect between two factors in a factorial experiment.
What is (a−1)(b−1)?
