[U4Q] Sandy, a BCBA, is determining the effectiveness of a differential reinforcement of other behavior (DRO) procedure on decreasing her client’s elopement. For every 5 minutes in which her client does not elope, they earn points. The amount of points her client earns varies based on the activity they are engaged in because the client appears to dislike some activities more than others. A week into implementing the DRO procedure, the client comes down with a cold. Despite this, Sandy still sees an immediate decrease in elopement and an increase in independent requests to take a break from her client. Which of the following is most likely to be an extraneous variable in this scenario?

[U4Q] Alicia, a BCBA, provides consulting services for a musician to help him improve his chord accuracy when playing the guitar.

However, Alicia believes the handheld clicker she has been using is not counting all of the times she presses the device and that this could be impacting the count number. Which of the following is the dependent variable in this scenario?
