Factorial Design Example. A design with p such generators is a 1l pl-p fraction of the full factorial design. In a factorial design multiple independent variables are tested.
2 IV s each with 2 levels for a total of 4 combinations or cells 2 by 2 factorial design different participants assigned to each cell calculate a mean score for each cell calculate marginal means to look for main effects plot cell means to. In triplicate this would be 192 tanks a huge undertaking. Full factorials are seldom used in practice for large k k7.
In a between-subjects design every participant experiences only one condition and researchers assess group differences between participants in various conditions.
An example of a full factorial design with 3 factors. In triplicate this would be 192 tanks a huge undertaking. In the fish farm example imagine adding another factor temperature with four levels into the mix. A 2k-p fractional design of resolution R will always project into a full factorial.
