525 ACTUAL EXAM PAPER 2026
QUESTIONS WITH ANSWERS GRADED
A+
◍ Y axis.
Answer: - vertical axis - also called ornate axis - dependent variable is
labeled on this axis
◍ Split Middle.
Answer: A method of identifying the trend in highly variable data.
◍ single case research.
Answer: examines changes within an individual's performance
◍ Trend.
Answer: The slope or direction of a data series within a condition.
◍ evidence based practice.
Answer: term used to describe when an intervention has gone through
rigorous, high quality experimentation and has been considered to be of
value for specific individuals and/or behaviors of interest
◍ independent variable.
Answer: term synonymous with intervention
◍ Level.
Answer: A within conditions pattern described as high, moderate, or low; an
indication of the amount of the behavior that occurs.
◍ dependent variable.
Answer: term synonymous with behavior
, ◍ variability.
Answer: A within conditions pattern meaning the range of values; the
opposite of stability.
◍ immediacy of change.
Answer: The degree to which behavior change is observed as soon as the
intervention is introduced.
◍ X axis.
Answer: abscissa (x axis)The horizontal axis on a graph.
◍ Overlap.
Answer: A between conditions analysis of the values of data in one
condition that are the same as those in an adjacent condition.
◍ internal validity.
Answer: considered high when there is clear experimental control
◍ experimental control.
Answer: when this is demonstrated, we have verified that there is a
functional relation between the independednt and dependent variables - that
the behavior causally (functionally) related to the implementation
◍ consistency.
Answer: The extent to which data patterns in one condition are similar to
data patterns in similar conditions.
◍ Percentage of non-overlapping data (PND).
Answer: the percentage of responses in the treatment condition that are more
extreme than the most extreme response in a relevant control conditionUsed
to calculate overlap.
◍ Partial Interval Recording.
Answer: is a measurement method that involves scoring the behavior as
occurring if it happens at any point during an interval.
◍ functional relation.
Answer: visually demonstrated (through visual analysis of the graphed data)
