STUDY GUIDE
●● ABA single-subject research design
Answer: Design beings with a period of baseline A, followed by an
intervention B, which is then followed by a return to baseline A; all
assessment phases, baselines or interventions in single-subject research
involve multiple or continuous assessments
●● ABAB single subject research design
Answer: Primary format for this design is the introduction of a clear
baseline setting or environment followed by introduction of the
intervention or independent variable: ABAB
●● accessible population
Answer: all individuals of the target population who can feasibly be
accessed for participation in a study
●● Alpha level
Answer: the level of (statistical) significance set by the researcher for
rejecting the null hypothesis
,●● Alternative directional hypothesis
Answer: A hypothesis that is based on previous research, theory, or
personal experience and that involves predicting the direction of the
outcome.
●● Alternative Hypothesis (H1)
Answer: A statistical hypothesis based on the rejection of the null
hypothesis
●● Alternative non-directional hypothesis
Answer: A prediction that there is a difference between research groups
but no direction is indicated
●● Analysis of Variance (ANOVA)
Answer: A parametric inferential statistical procedure designed to
compare differences between the means or two or more groups
●● Analysis of Covariance (ANCOVA)
Answer: A statistical calculation comparing differences of means
between two or more groups that statistically controls for one or more
extraneous variables; results are reported in adjusted means for the
groups, based on the influence or effects of the extraneous variables
●● Baseline
, Answer: the natural level of performance as measured from the
dependent varible of the sample prior to introduction of the independent
variable or an intervention
●● Case study
Answer: a detailed investigation of an individual, group, organization, or
other assemblage
●● Chi-square
Answer: A nonparametric inferential statistical procedure designed to
determine whether collection data (nominal data) is significantly
different from what was expected
●● Cluster sampling
Answer: a sampling technique in which a sample is chosen of naturally
occurring groups or intact units, and all individuals in the group are
studied
●● Collectivism
Answer: a worldview that groups provide support for members and
provide a structure of care
●● Concurrent validity
