When someone institutes an intervention, a condition change line shows the intervention along with the name of the intervention. A performer, for instance, may receive a reward after meeting her daily frequency aim (goal) each day. Her new condition has a name called “Daily reward.” A condition change line visually signals the advent of a new condition.
A chart reader analyzes the effect of an intervention by inspecting the data appearing after the condition change line. Chartlytics shows a condition change line with a red line ending with a small 90 degree line to the right (and the name of the condition).
How to add a condition change line
First, (1) click on the performers link and then (2) select the specific performer for whom you would like to enter an intervention or annotation.
An intervention means significantly altering the course of events for the Performer. An intervention could include a change to materials, practice procedures, or perhaps a medical intervention (medication change like ADHD meds). The Performer, Manager, Advisor, and Supervisor can determine the differences between intervention and annotation.
Interventions do affect change measures (e.g., celeration, bounce, A.I.M.). Once an intervention occurs on the chart, all of the change measures (e.g., celeration, bounce, A.I.M.) for the previous condition will stop and a new set of change measures will appear for the new condition.
Condition change lines also allow chart readers to determine the effects of changes from one condition to the next with FrequencyMultipliers, Celeration Multipliers, Bounce Change, and A.I.M. Change.
