questions and answers
verified 100%
1. threats to internal validity include: history, maturation, testing, procedural
infidelity
2. match
• events that occur during the experiment but that are not related to planned
procedural changes that may influence the outcomes.
history
• changes in behavior due to the passage of time:
maturation
• occurs when participants need to respond to the same test repeatedly
during a baseline or probe condition, which influences responding: testing
,• threats related to the measurement system, and are of concern because of
repeated measurement by human observers who may make errors:
instrumentation
• inconsistent implementation of the experimental condition: procedural
infidelity
• the loss of participants during a study, which limits the generality of
findings: attrition.
• occurs when a participant’s behavior is influenced by more than one
planned intervention during the course of a study: multiple treatment
interference
• a type of data instability that refers to a repeated and predictable pattern in
the data series over time: data instability
3. carry over effects: both an and b
4. the hypothesis that assumes that sample observations are influenced by some
non-random cause is: the alternative hypothesis
5. amanda is an rbt at an aba clinic. they are working with a client, jerrell, to
decrease aggressive behaviors (i.e., biting others). they have 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) mean =
18 , median =16, mode = 31 ,32
6. 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 schoolyear 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 concluded that the
good behavior game had no impact on student disruptive behavior, when in fact it
had. this is an example of: a type 2
error
7. the primary purpose of the method section is to: both and
b
8. which of the following is true about single-case research design? the
participant serves as his or her own control
