SPCE 630 UPDATED EXAM SCRIPT 2026 QUESTIONS AND
SOLUTIONS GRADED A+
✔✔When using MTS, occurrences of the target behavior are recorded if the behavior
occurs - ✔✔at the end of the interval
✔✔If observers do not agree on behavior occurrences when collecting data (low IOA),
which common problems could be present? - ✔✔observer bias, error, observer drift
✔✔Whole interval recording tends to - ✔✔underestimate behavior occurrences
✔✔Which type of validity refers to whether or not the measurement procedures
accurately reflect the target behavior being measured? - ✔✔construct validity
✔✔Reliability and validity refer to the same concept - ✔✔false
✔✔Which of the following is the best example of a non-reversible dependent variable? -
✔✔reading sight words
✔✔Researchers can write non-examples of target behaviors in order to help increase -
✔✔treatment integrity
✔✔Which type of IOA is calculated when researchers only look at intervals either or
both observers did NOT observe the target behavior? - ✔✔unscored-interval IOA
✔✔Which is a measurement of whether the intervention was conducted as intended? -
✔✔treatment integrity
✔✔Measurement of procedural fidelity does all of the following except - ✔✔Helps
cilnicians avoid emphasizing "train and hope"
✔✔The extent to which experimenters trained implementers as planned is known as -
✔✔implementation fidelity
✔✔the degree to which procedures of all experimental conditions are implemented as
intended is known as - ✔✔procedural fidelity
✔✔Summative analysis of treatment procedural fidelity increases which type of validity?
- ✔✔Internal
✔✔Common ways to measure treatment integrity include - ✔✔checklists, self-reports,
direct systematic observation
, ✔✔A 5-year-old boy diagnosed with ASD started receiving ABA services. Which of the
following is NOT a stakeholder in the evaluation of social significance? - ✔✔His BCBA
✔✔When measuring social validity, which of the following are more subject to bias? -
✔✔participant/stakeholder judgements
✔✔What type of evidence should procedural fidelity provide? - ✔✔adherence and
differentiation
✔✔Teaching socially important goals does which of the following? - ✔✔teaches patients
to engage in behaviors valued by society
helps improve participant quality of life
helps improve quality of life of those who interact with participants
✔✔The null hypothesis states that - ✔✔any difference in the groups is due to chance
✔✔Results of group design yield - ✔✔a statistical relationship between the IV/DV
✔✔Researchers want to determine if sleep deprivation affects exam scores in college
students. The researchers plan to calculate a test statistic. Which would be a more
appropriate study design - ✔✔Group design
✔✔Researchers want to know if providing noncontingent attention will reduce a 3-year-
old's attention-maintained physical aggression. The researcher will use visual analysis.
Which would be a more appropriate study design? - ✔✔Single case research design
✔✔Measures of central tendency include which of the following (check all that apply -
✔✔mean, median, mode
✔✔Measures of dispersion include which of the following (check all that apply): -
✔✔standard deviation, variance, range
✔✔Steps of sampling include which of the following (check all that apply) - ✔✔defining
the population
defining the sample
determining the sample size needed (use power and effect size)
determining the method for pulling the sample
✔✔Which type of sampling error refers to a lack of true understanding of the population
researchers want to study? - ✔✔population error
