SPCE 630 Questions with Correct Answers Latest Updated 2024/ Verified Threats to internal validity include: - Correct Answer History, maturation, testing, procedural infidelity Events that occur during the experiment but that are not related to planned procedural changes that may influence the outcomes. - Correct Answer History Changes in behavior due to the passage of time. - Correct Answer Maturation Occurs when participants need to respond to the same test repeatedly during a baseline or probe condition, which influences responding. - Correct Answer Testing Threats related to the measurement system, and are of concern because of repeated measurement by human observers who may make errors. - Correct Answer Instrumentation Inconsistent implementation of the experimental condition. - Correct Answer Procedural Infidelity The loss of participants during a study, which limits the generality of findings. - Correct Answer Attrition Occurs when a participant's behavior is influenced by more than one planned intervention during the course of a study. - Correct Answer Multiple Treatment Intreference A type of data instability that refers to a repeated and predictable pattern in the data series over time. - Correct Answer Cyclical Variability Carryover effects: - Correct Answer NOT: Is best described as the effect of a procedure used in one condition on responding in an adjacent condition.The hypothesis that assumes that sample observations are influenced by some non-random cause is: - Correct Answer The alternative hypothesis 1 / 2
Amanda is an RBT at an ABA clinic. She is working with her client, Jerrell, to decrease aggressive behaviors (i.e., biting others). She has collected data for the frequency of Jerrell's bites for three weeks.Calculate the mean, median, and mode of the following data set (round to the nearest whole number):
Week 1: 22, 31, 20, 32, 32
Week 2: 7, 8, 13, 31, 17
Week 3: 16, 5, 9, 12, 15 - Correct Answer Mean = 18, Median =16, Mode = 31, 32
Dr. Jones wanted to know if the use of the Good Behavior Game decreased rates of disruptive behaviors in an elementary school. Dr. Jones collected data throughout the duration of the school year across two elementary schools. In school A, all k-6 classrooms used the Good Behavior Game. In School B, no classrooms used the Good Behavior Game. At the end of the school year, Dr. Jones shouted, "Eureka!The Good Behavior Game works," when in fact it had no impact on student disruptive behavior. This is
an example of: - Correct Answer A Type I Error
