    Rival Causal Factors:

    In experimental design, rival causal factors are any variables other than the treatment that may be responsible for the outcome or results. In other words, something else produced the result other than the variable that was hypothesized to produce the result. For example, history, maturation, and selection bias can all be rival causal factors.

    Internal rival causal factors are factors within a study that can invalidate ...
