Amanda is an RBT at an ABA clinic. They are working with a client, Jerrell, to decrease aggressive behaviors (i.e., biting others). They have collected data for the frequency of Jerrell’s bites for three weeks. Calculate the mean, median, and mode of the following data set (round to the nearest whole number): Week 1: 22, 31, 20, 32, 32 Week 2: 7, 8, 13, 31, 17 Week 3: 16, 5, 9, 12, 15 Mean =16, Median = 16, Mode = cannot be determined Correct Answer Mean = 18, Median =16, Mode = 31, 3...

Which of the following scenarios best exemplifies a threat to external validity in a research study?a. Participants dropping out of a study at different rates across experimental groups. b. Participants altering their behavior because they are aware they are being observed. c. The use of a non-representative sample that limits the generalizability of the findings. d. Inconsistent application of the experimental procedure across participants. e. Measurement instruments yielding different r...

Match the clue to the correct answer. Group of answer choices Repeating the experimental effect with the same participant more than once in the same study. Direct intra-subject replication Repeating the experimental effect in the same study with different participants. Direct inter-subject replication The use of a systematic process of replication designed to identify effective intervention packages that are effective with a range of individuals in the target population. Clinical repli...

Match the scenario to the most likely threat to internal or external validity. Group of answer choices A school holiday interrupts the intervention, potentially impacting outcomes. History The research assistant uses different observation criteria across phases of the study. Instrumentation Results are based on an after-school program that may not apply to regular classroom settings. Setting generalization The study includes only students who already have high motivation, which might not...

Data from Eleanor's study on the effectiveness of a check-in/check-out system in reducing disruptive behavior is shown above. The data shows an elevated percentage of points at the beginning of the study and starts to drop off following the intervention.Figure 2: Above you can see the data that was collected on Brooks’ shows how disruptive behavior was reduced using CICO. During the baseline and withdrawal stages, the graph shows a great deal of variation in responses. Steady and high-q...

Samar's BCBA wanted a way to describe the damage that their client was doing to themself with the self-injurious behaviors they exhibited. The client was prone to pinching their arms with the thumb and forefinger. The BCBA instructed the behavior therapists to record the pinching as "leaves no mark," "leaves a slight pink mark," "leaves a bright red mark," and "draws blood." The BCBA wanted the therapists to record a measure of what for them? Correct! Magnitude ...

Put the steps to conducting a systematic visual analysis in the order in which they should be completed. Correct! Analyze level, trend, and variability within each condition Correct! Analyze consistency of change across conditions Correct! Make summative conclusion Correct! Determine if graph has been constructed appropriately Correct! Analyze level, trend, and variability across adjacent conditions Correct! Examine research questions Correct! Review number of data points

dentify the goals of behavior analysis as a science (i.e., description, prediction, control) A.2. Explain the philosophical assumptions underlying the science of behavior analysis (e.g., selectionism, determinism, empiricism, parsimony, pragmatism). C.3. Measure occurrence C.4. Measure temporal dimensions of behavior (e.g., duration, latency, inter-response time). C.5. Distinguish between continuous and discontinuous measurement procedures C.6. Design and apply discontinuous measurement ...
