Here is a hypothetical baseline and treatment data set reflecting the Time Sampling data collection method for Kelly's body rocking behavior. Baseline Data (over 5 days, 30-minute observation periods, 1-minute intervals): Day 1: 18/30 Day 2: 20/30 Day 3: 22/30 Day 4: 19/30 Day 5: 21/30 Treatment Data (over 5 days, 30-minute observation periods, 1-minute intervals): Day 1: 15/30 Day 2: 14/30 Day 3: 12/30 Day 4: 13/30 Day 5: 11/30 Explanation: In this hypothetical data set, the baseline data represents the frequency of body rocking behavior before any intervention was implemented. The numbers represent the number of 1-minute intervals during which the behavior was observed in a 30-minute period. For example, on Day 1, body rocking was observed in 18 out of the 30 intervals. The treatment data represents the frequency of body rocking behavior after the implementation of an intervention. As you can see, the frequency of body rocking behavior has decreased during the treatment phase compared to the baseline phase, suggesting that the intervention may be effective
