In single subject design the primary criterion for inferring causality is concomitant variation; that is, the observed change in the outcome must occur at (or soon after)the time the intervention is implemented.

Concomitant Variation

A phenomenon where changes in one variable are associated with changes in another variable, suggesting a possible correlation or causal relationship.


The relationship between cause and effect, where one event (the cause) brings about another event (the effect).

  • Acquire an understanding of the elementary concepts and stages in single-subject design.
  • Understand the critical need for precise evaluation of changes in collective processes.

Final Answer :
Explanation :
In single subject design, causality is inferred through concomitant variation, meaning the change in the outcome is observed to occur in conjunction with, or soon after, the implementation of an intervention, indicating a potential causal relationship.
