ABA Behavioral Evaluation & Data Collection 3

Question 1

A BCBA records the number of times a student raises her hand during a 30-minute class. Which measurement dimension is being captured?

Accepted Answer

Frequency (count)

Answer

Frequency (count) records the total number of discrete occurrences of a behavior within an observation period.

Question 2

When a behavior analyst calculates IOA for event recording, the most common formula is:

Accepted Answer

Smaller count ÷ larger count × 100

Answer

For event recording, IOA is calculated by dividing the smaller count by the larger count and multiplying by 100 to get a percentage.

Question 3

Which data display format is most useful for visualizing trends and changes in behavior over time in ABA practice?

Accepted Answer

Line graph

Answer

Line graphs are the standard display in ABA because they clearly show trends, level changes, and variability over sequential time points.

Question 4

An FBA reveals that a child's elopement is maintained by escape from academic tasks. The BCBA should next:

Accepted Answer

Design a competing behavior pathway and intervention

Answer

After identifying the function through FBA, the BCBA develops a behavior intervention plan based on a competing behavior pathway targeting that function.

Question 5

Whole interval recording is likely to underestimate the true prevalence of a behavior when:

Accepted Answer

The behavior is brief and does not fill entire intervals

Answer

Whole interval recording only scores an interval as positive if the behavior persists for the entire interval, underestimating behaviors that occur briefly.
