The upshot is that random assignment to conditionsalthough not infallible in terms of controlling extraneous variablesis always considered a strength of a research design. every possible order (n!, e.g., AB = 2! The range of values for your levels may impact performance (typically best performance in middle of range). One is that each participant has an equal chance of being assigned to each condition (e.g., a 50% chance of being assigned to each of two conditions).

This matching is a matter of controlling these extraneous participant variables across conditions so that they do not become confounding variables. Matching is a more complex process, and it will always be very difficult to match participants identically. Thus random assignment plays an important role in within-subjects designs just as in between-subjects designs. However, there are some reasons that this possibility is not a major concern.
