nonrandom

Not by chance

Nonrandom describes something that follows a pattern, purpose, or design rather than occurring by chance.

In statistics and science, nonrandom sampling or selection involves deliberate criteria: The nonrandom assignment of patients to treatment groups introduced bias.

More broadly, it suggests intentionality where randomness might be expected: The distribution of errors seemed nonrandom.
