Unit 9 Multifactorial ANOVA Flashcards
A factor is a…
Qualitative predictor variable
Each factor has a certain no. of levels that are…
groups
Treatments are…
A specific experimental condition: determined by factors and levels of each factor… combinations of factor levels
The experimental unit is the
smallest unit to which a treatment can be assigned
Balanced design is when…
treatment is replicated the same number of times in each treatment level
4 types of experimental designs:
Factorial: fixed factors, crossed designs.
Randomized block: (random factor = blocks)
Repeated measures: (random factor = subject)
Hierarchical nested: (random nested factors)
Fixed factor:
Levels chosen in advance of the experiment or are defined by the experiment (lvls of temperature)
Random factors
Are treated differently: levels are chosen randomly from a large population of possible levels
Multifactorial analysis experiment designs
Randomized complete block designs
Nested designs
