A factorial design can be either: Full (all possible interactions) or, Fractional (without all interactions, but some). Therefore, a "factorial design" does not necessarily implies it is "fully crossed". In the OP's case, where: two factors A and B are crossed, if every level of A can occur in every level of B. It will be a full factorial design.
Jul 10, 2020· The 2 k factorial design is the simplest type of factorial design, which involves two or more independent variables (named factors (k)) in two levels (+1 and −1), being very useful during the initial stages of the study when there are many variables to investigate, providing the lowest number of runs in a complete factorial design (Calado and ...
