A 2k factorial design is an experimental setup used in statistics to evaluate the effects of k factors, each at two levels (commonly labeled as low and high). This design allows researchers to systematically study the interactions between factors by running a full set of experiments at all combinations of factor levels, resulting in 2^k total experimental runs. It is particularly useful for identifying the optimal conditions and understanding how variables interact in multifactorial experiments. The simplicity and comprehensive nature of this design make it a popular choice in various fields, including agriculture, manufacturing, and product testing.

Factorial designs
In a 2 x 3 factorial design, there are two factors: one with 2 levels and another with 3 levels. Each factor represents a main effect, so there are a total of two main effects in this design. Additionally, there is the possibility of interaction effects between the two factors, but that does not change the number of main effects.
