When visually evaluating data from a single-subject study, which of the following graphical patterns would strongly suggest that a treatment is effective?

A researcher evaluating a single-subject study observes a high, increasing trend of anxiety during the baseline phase. When the intervention is introduced, the data shows an immediate shift to a lower, decreasing trend. Upon reinstating the baseline, the anxiety returns to a high level. True or False: According to the principles of visual inspection, this pattern of data provides strong evidence that the treatment was effective.

A researcher is analyzing graphical data from several single-subject studies to evaluate treatment effectiveness based on level, trend, and latency. Rank the following patterns from the STRONGEST evidence (1) to the WEAKEST evidence (4).

In single-subject research, why is a 'continuous trend' that persists from the baseline phase into the treatment phase generally interpreted as evidence of an ineffective treatment?

A researcher analyzing a graph from a single-subject study observes that the trend established during the baseline phase continues unchanged throughout the treatment phase, with no significant shift in data level. Based on the criteria of visual inspection, the researcher would evaluate this treatment as _____.

In single-subject research, visual inspection is used to judge whether a treatment caused a change in behavior. Match each graphical data pattern with the conclusion it best supports.

In single-subject research, when using visual inspection to determine whether a treatment was effective, researchers evaluate three primary characteristics of the data: level, trend, and _____.
