Lab 3 - Experimental Design and ANOVA Flashcards
1
Q
types of common experimental designs
A
- completely randomized design
- randomized complete block design
- latin square
- split plot design
2
Q
completely randomized design
A
- treatments are assigned randomly so that each treatment has the same chance of receiving any one treatment
- simplest design, low error
3
Q
when is completely randomized design best used
A
best for experiments where experimental materials are homogenous and not heterogenous
4
Q
what experimental design is this
A
completely randomized design
5
Q
randomized complete block design
A
- uses blocking/grouping of similar experimental units where each block is the same size and equal to the number of treatments
- each treatment is randomly assigned t 1 experimental unit in every block
- helps with heterogeneity
6
Q
what type of experimental design is this
A
randomized complete block design
7
Q
latin square
A
- 2 blocking/groupings of treatment and experiments, where for every treatment, there is a replicate
- treatment occurs once in every row and column
8
Q
when is the latin square design most suitable
A
when there are a small number of entries/treatments
9
Q
what type of experimental design is this
A
Latin square
10
Q
split plot design
A
main plot treatments are randomly assigned to main plots and then the subplot treatments are randomly assigned in each main plot
11
Q
what type of experimental design is this
A
split plot design
