EDF 6437 FINAL EXAM LATEST
QUESTIONS AND
ANSWERS 2026 - 2027
whole interval recording is likely to do what? - ANSWERS-
underestimate behavior
trials to criterion - ANSWERS-number of responses opportunities
needed to achieve a predetermined level of performance. compares
effectiveness
disadvantages of discontinuous measures - ANSWERS-artifacts,
different procedures will produce different results, variability in your
data
threats to measurement validity - ANSWERS-indirect measurement,
measuring a behavior other than the behavior of interest, measuring in a
way that is not appropriate for the response. requires assumptions are
made about the behavior and measurement
IOA - ANSWERS-the degree to which two or more independent
observes report the same values for the same event. increases
believability of data

QUESTIONS AND
ANSWERS 2026 - 2027
total count IOA - ANSWERS-a comparison of two totals are compared
from each observer and the complete amount is reported
mean count per interval IOA - ANSWERS-the average is taken from
each interval and compared. not good with outliers in collection, but
provides a good estimate
exact count IOA - ANSWERS-each interval must match to score. very
conservative method that will lower total agreement in practice
trial by trial IOA - ANSWERS-number of trials in agreement over total
number of trials. not commonly used but good for DTI
total duration IOA - ANSWERS-shorter interval divided by longer
interval. high total duration doesn't assure same durations for the same
behaviors occurred
mean duration by occurrence IOA - ANSWERS-each response is
calculated. ore conservative. follows smaller divided by larger for each
response, then summed, then x100 and round

QUESTIONS AND
ANSWERS 2026 - 2027
interval by interval IOA - ANSWERS-each interval is matched from
primary observer and secondary. total number agreed/total agreed +
disagreed. non occurrence counts
scored interval IOA - ANSWERS-only scored when both observers
agree some amount of behavior occurred. unscored by one is a
disagreement. actual number is no important, only if it happens or
doesn't. will skew
unscored interval IOA - ANSWERS-nonoccurrence of behavior is
considered. only counts when both observers record the nonoccurrence
for the same interval
in what order should you consume a research paper? - ANSWERS-
results --> methods --> discussion --> introduction
good lines graphs - ANSWERS-vertical axis labeled with quantitative
measure and horizontal axis is labeled with a unit of time; vertical axis
length has a 2:3 ratio to the horizontal axis; tic marks pointed outward;

QUESTIONS AND
ANSWERS 2026 - 2027
tick marks have labels; a minimal number of evenly spaced tick marks;
data points clearly visibly; data paths clearly visible; condition change
lines; condition labels; figure caption
single case design - ANSWERS-repeated and systematic presentation
and removal of a treatment. continue to measure behavior. variety of
effects to determine how well something is working
pros to SCD - ANSWERS-repeated measurement, determines patterns,
does not need to lump similar characteristics, very conservative way to
determine results
when should phase changes be introduced? - ANSWERS-when steady
state responding occurs
latency to change - ANSWERS-the last point in baseline to the first in
treatment. the more dramatic the better
problems with ABAB design - ANSWERS-some behavior can't be
reversed to baseline
