[U4Q] Lola wants to determine whether implementing a public posting system or an incentive system would be more effective for improving employee attendance. She implements the public posting system for 4 weeks, then implements the incentive system for 4 weeks, and then compares rates of employee attendance. This is an example of which type of analysis?

[U2Q] Corey receives a text from his boss and responds 15 seconds later. This is an example of:

[U2Q] Vincent is teaching a painting class. He wants to track how many of his students are painting during the final 20 minutes of class. Every 3 minutes, he looks at his students and counts how many are actively painting. Which recording method did Vincent use?

[U4Q] Review the baseline data illustrated below. Which continuing data path best predicts future behaviors of concern in the absence of intervention?

[U4Q] Raine, a BCBA, is running a study that teaches task engagement during circle time activities. She is using a concurrent multiple baseline design and starts the study with five participants. Raine systematically introduces a timer that goes off every 60 seconds. The timer is attached to each participant and is designed to prompt the child to do a self-check for task engagement during the intervention phase. Raine simultaneously collects data on eye contact and if the child’s body is facing the circle time leader. Halfway through Raine’s study, one of the participants moves to a different school and is unable to continue participating in the study. In this scenario, which of the following is most likely an example of attrition? 

[U2Q] Darnell records how many times she practices her 1-minute flashcard timings until she reads 15 cards in 1 minute three consecutive times across 5 days. These data should be reported as:

[U2Q] Kerala wants to monitor an employee’s off-task behavior. More specifically, Kerala is interested in the personal conversations that take place after the employee’s lunch break.

As part of the celebration, school administrators instruct the educators not to give their students homework for the week. During the same week, Shannon tests different ways to measure student participation. Which of the following is most likely to be an extraneous variable in this scenario?
