Resumo	Celeration line analysis is a single-case method that fits a trend line to the baseline phase, projects that line forward into the intervention phase, and judges effect by how many intervention data points fall on the improvement side of the projected trend. Built on Owen White's split-middle technique from precision teaching and codified for social-work practice by Bloom, Fischer, and Orme, it directly addresses a weakness of level-only comparisons: it asks whether the client improved beyond the trajectory the baseline was already on, and pairs the count with a simple binomial test for statistical decision-making.	Visual analysis is the primary method for judging whether an intervention produced an effect in single-case and single-system designs: the data are plotted as a time series across baseline and intervention phases and read systematically for changes in level, trend, variability, immediacy of effect, overlap between phases, and consistency across similar phases. Rooted in applied behavior analysis and codified by the What Works Clearinghouse single-case standards, it treats the graph itself as the evidence and reserves the label 'effect' for changes that are clear, replicated within the design, and unlikely to reflect ordinary fluctuation.
