Design
The single subject design
What is the back bone of practice evaluation
The levels of measurements
What is nominal (categories), Ordinal (categories in a certain order), Interval (equal intervals) and Scale (equal intervals and 0 points)
The three causality conditions must be established before we call a relationship causal
What are:
Relationship must exist between the two variables
The relationship must be non-spurious
There should be a time to interval between one variable and the other
The phase of baseline
What is phase within single subject design. The phase is one in which the researcher collects data on the dependent variable without any intervention in place
The B design
What is the period of time during which an outcome is measured repeatedly in the absence of the intervention.
The two types of SSD's
What has there been change in the area of concern?
What is there a functional relationship between the intervention and observed change?
The key characteristics that all measurements strive for
What is validity, readability, measurement error, utility and directness
The intent of a casual association
What is full explanation: in statistics an associations on means there a relationship between to variables or factors.
The two phases of AB intervention
What is Non-intervention baseline phase (A) and an Intervention Phase (B).
The purpose of multiple baseline designs
What is the determination of whether the problem is getting better or worse and provides an estimate of what would happen to the client without intervention.
What would you see during practice?
What you will not see in practice is the problems. You will see indicators of problems.
The two errors you can encounter while taking measurements
What is random: by chance, normal fluctuations, cancel each other out
What is systematic:bias, average score is influenced into a particular direction.
The need to prove causation
What is randomized experiment
The three ABA design
What is the three phase design: 1-non-intervention baseline phase(A), 2-Intervention phase (B), and 3- no-intervention withdrawal phase (A)
The situations in which no patter is evident
What are measures , inconsistencies and changes ?
The determination of a causal relationship
What is perform randomization test?
The use of BAB design
What is an individual behavior so severe that the researchers cannot wait to establish a baseline and must begin with intervention.
