SPCE 630 EVALUATION EXAM 2026 QUESTIONS AND
SOLUTIONS GRADED A+
✔✔Two observers recorded whether hand-flapping occurred or did not occur during an
interval. Calculate IOA based on the Interval by Interval Method. - ✔✔40%
✔✔What is a primary reason for replicating the findings of a study: - ✔✔To assess the
reliability of the findings
✔✔Which of the following is an advantage of using percentage data over numbers? -
✔✔More familiar to people than other measures and facilitates communication of
performance
✔✔Which of the following is true about partial interval data recording? - ✔✔It has a
tendency to over-estimate the occurrence of behavior
✔✔Based on the information provided above, this article is likely an example of which of
the following types of articles: - ✔✔A review article detailing what is known about
medications for individuals with Autism Spectrum Disorder and other developmental
disabilities
✔✔Internal validity of a study depends on: - ✔✔The attempts by the researcher to
ensure plausible reasons for behavior change, other than planned experimental
changes, are controlled for.
✔✔Experimental designs: - ✔✔Require systematic manipulation of an independent
variable and careful measurement of the dependent variables.
✔✔The primary goal of a single case research design is: - ✔✔To determine whether a
casual or functional relationship exists between a research manipulated independent
variable and a meaningful change in the dependent variable
✔✔Informed assent: - ✔✔Includes obtaining consent from minors who are not yet old
enough to enter into a contract
✔✔Dr. Tingstrom is interested in evaluating the effectiveness of tootling for increasing
positive peer reporting in an elementary classroom. He collects data in Mrs. Dobbs's
fourth grade classroom. He hopes to demonstrate the same effects of tootling with the
same classroom more than once in the same study. Specifically, he hopes that
behaviors are at similar levels when the intervention is in place compared to when it is
withdrawn. This is an example of: - ✔✔Direct-intra subject replication
, ✔✔Which of the following statements are true regarding treatment integrity? - ✔✔An
overall treatment integrity level at or above 80% has been proposed as criterion for
acceptable research, although there are little data to support this criterion
✔✔A researcher repeatedly observes children with and without autism spectrum
disorder (ASD) during recess. She notices that children with ASD are more likely to join
in play with other children when the children without ASD initiate the social interaction.
She concludes that there is a correlation between joining in play and who initiates the
interaction. Which level of scientific understanding is the researcher using? -
✔✔Prediction
✔✔Professor Smith wants to increase time working on research-related activities by
implementing a structured schedule, self-monitoring, and goal setting. What is/are the
independent variable(s)? - ✔✔Structured schedule, self-monitoring and goal setting
✔✔Well-designed applied research studies allow for: - ✔✔Replication of findings from
other studies under similar and novel conditions
✔✔A BCBA is interested in evaluating the use of fidgets to decrease vocal stereotypy in
a student with ASD. Prior to conducting her study, she conducts a literature review to
identify existing research. She is struggling to find articles on this topic. Which of the
following are strategies that she could use to help her find literature on this topic? -
✔✔She can use the "Background Information" pages to find titles that can provide her
with terms, names, and dates that can help her to search effectively for more in-depth
information
✔✔Identify the citation in correct APA format (7th edition) - ✔✔Vincent, L. B., Openden,
D., Gentry, J. A., Long, L. A., & Matthews, N. L. (2017). Promoting Social Learning at
Recess for Children with ASD and Related Social Challenges. Behavior Analysis in
Practice(italicized), 11(1)(italicized), 19-33. doi: 10.1007//s40617-017-0178-8
✔✔A teacher is trying to determine if Erica has mastered a mathematical task she has
been taught. She asks the aid to collect data on her completing this task during her
session with Erica. The aid will record each correct response. Which measurement
system is the aid using? - ✔✔Event Recording
✔✔Todd is a BCBA employed at an ABA Center. He is working with a client who
engages in high rates of vocal stereotypy. Todd would like to implement an intervention
that includes response interruption and redirection. To determine if this intervention is
effective, he will use a multiple baseline design across settings. He will collect data for
25 minutes each day. His observation will be divided into 15-second intervals. During
each interval he will code vocal stereotypy as occurring if it occurs for any duration of
the 15-second interval. Based on the literature, Todd's estimate of the percentage of
