[U5Q] A BCBA is teaching their client how to use the toilet. She collects baseline data and determines that the potential for accidents is high. She then implements an intervention that requires the client to wear underwear instead of the diaper the client currently wears. After the BCBA puts the intervention in place, the frequency of accidents begins to decrease.  Once the client consistently uses the toilet properly and accidents are rare, the BCBA implements a differential reinforcement for alternative behavior (DRA) procedure. The frequency of accidents initially remains low but begins to increase (trend back up) after a few sessions of DRA. Which confound is most likely influencing these results?

[U6Q] Sophia, a BCBA, is analyzing data to determine the success of an intervention. She reviews her research question, determines if there are sufficient data in each condition, and looks for variables that may have affected the data both within and across conditions. During her analysis, she sees that her research assistants are inputting graphical data at different scales, rendering visual analysis of the data impossible. What step in performing a visual analysis should Sophia have taken before reviewing her research question? 

[U6Q] What can we conclude from the data presented in the following graph?

[U1Q] Tana wants to be a special education teacher. She will need a degree in special education to be able to work in the public school district near her residence as well as get relevant job offers. She will need to complete the rest of her coursework at the university and apply for jobs. Which of the following is an intermediate outcome in this scenario? 

[U1Q] Mallorie wants to attend a 4-year state university. In order to do this, she knows she will have to qualify for the Bright Futures Scholarship, which requires a 3.0 GPA and 100 hrs of community service. Her guidance counselor helps her in setting the following goals: Mallorie will complete the volunteer application and sign up for one volunteer opportunity by the end of the first quarter, and she will pass each test in her classes with an 80% or higher, or request a retake if she scores below 80% in the first quarter. Which of the following is the short-term objective in this scenario?

[U6Q] Amanda is teaching one of her clients to play independently with a variety of toys for a duration of at least 10 minutes. She implements an activity schedule as a prompt. At the end of the study, Amanda analyzes the graphed data and notices that her client’s independent play with toys only increases when she uses the activity schedule. Which type of analysis is Amanda conducting?

[U6Q] Karen, a BCBA, is reviewing the data collected on an intervention that she put in place to increase the accuracy of discrete trial training implementation during sessions by staff. She determines that the accuracy of intervention has remained stable between 80%–95% since the start of the intervention phase. What type of analysis is Karen conducting? 

[U6Q] Wilhelmina, a BCBA who works in a group home, introduces a feedback system to improve her staff’s performance when teaching life skills to residents. She looks at the baseline- and the intervention-phase data to determine if the changes are in the direction she intends, and whether there are significant changes in performance levels. Which type of analysis is Wilhelmina conducting?
