Statistical Analysis in Single-Subject Research

What is the primary method of data analysis used in single-subject research to determine the effect of the independent variable?

In single-subject research, visual inspection is used to calculate the statistical significance (p-value) of an independent variable's effect.

A researcher is conducting a visual inspection of a graph from a single-subject study to determine the effect of an intervention. Match each observation of the data with the corresponding component of visual inspection being applied.

Arrange the following hypothetical outcomes of a visual inspection in order from the pattern that provides the weakest evidence of a treatment effect to the pattern that provides the strongest evidence of a treatment effect.

You are tasked with designing the data analysis protocol for a new single-subject research study. To correctly establish a visual inspection methodology, which of the following procedures should you construct?

Arrange the steps of visual inspection in single-subject research in the correct chronological order, as they are typically performed during data analysis.

A researcher studying a participant's social anxiety observes that the participant initiated 10 conversations per day during the baseline phase and 11 per day during the treatment phase. If the researcher concludes the therapy was ineffective because this slight change was not large enough to be clearly seen on the graph, they are evaluating that the therapy did not have a(n) _____ effect.

In single-subject research, instead of using inferential statistics to evaluate group differences, researchers rely on ____ to analyze graphs of individual participant data and determine the treatment's effectiveness.

A researcher uses an AB design to evaluate the effectiveness of a behavioral intervention on a student's off-task behavior. During the baseline (A) phase, the student's off-task behavior shows a steady, prominent downward trend. When the intervention (B) is introduced, the behavior continues to decrease at the exact same rate. If the researcher concludes through visual inspection that the intervention caused the reduction in off-task behavior because the behavior is lower during the treatment phase than it was at the start of baseline, this application of visual inspection is correct.

In single-subject research, visual inspection requires analyzing specific graphical patterns to determine if a behavior change can be causally attributed to the intervention. Match each visual pattern observed during data analysis with its corresponding methodological implication for drawing causal conclusions.
