Single-Case Design Data Generator

Study

Dependent variableWhat you are measuring. Unit of measureThe scale of each data point.

Direction

Increasing a skill
The number should go up (e.g., speech sound production, making requests). Decreasing a behavior
The number should go down (e.g., aspiration, disfluencies).

Variability is set randomly for each participant and is not shown, so you can calculate and interpret it from the data.

Session number runs down the left; each phase is its own column. Blank cells mean that participant was in a different phase (or not probed) that session. Regenerate for a fresh random draw.

Set up your study on the left and select Generate data. You'll get a table with Session down the side and a column for each phase, staircased so a later participant's intervention starts after a longer baseline. Then graph and interpret it yourself.
