DataCamp Experimental Design in R Latin squares Two blocking factors (instead of one) All factors must have the same number of levels Key assumption: the treatment and two blocking factors do not interact Analyze like a RCBD

DataCamp Experimental Design in R EXPERIMENTAL DESIGN IN R Factorial Experiments Kaelen Medeiros Product Data Scientist at DataCamp

DataCamp Experimental Design in R Factorial Designs 2 or more factor variables are combined and crossed All of the possible interactions between levels of factors are considered as effects on the outcome Example: high/low water and high/low sunlight's effect on plant growth.

DataCamp Experimental Design in R Factorial Example

DataCamp Experimental Design in R 2^k factorial experiments 2^k factorial experiments involve k factor variables with 2 levels It results in 2^k number of combinations of effects to test Analysed with a linear model and ANOVA Also use TukeyHSD() to determine which combinations are significantly different

DataCamp Experimental Design in R EXPERIMENTAL DESIGN IN R What's Next For Experimental Design Kaelen Medeiros Product Data Scientist at DataCamp

DataCamp Experimental Design in R What's Next? Other factorial designs (besides 2^k) including fractional factorial designs Experiments with random factors Nested designs Split plot designs Lattice designs

DataCamp Experimental Design in R EXPERIMENTAL DESIGN IN R Go forth & design experiments!
