Nominal: categories Ordinal:categories in a certain order Interval: equal intervals Scale: equal intervals and 0 point
What is the levels of measurements?
100
What client would like to do, be or prefer to happen after the intervention is complete.
What is ultimate goals?
100
Allows for evaluation across clients, situations or problems True experimental design in that it allows for casual inference Useful for evaluating situations where an intervention would be likely to bring about enduring changes in the dependent variable
What is multiple baseline designs?
200
Validity Reliability Measurement Error Utility Directness
What is key characteristics of all measurements?
200
Very specific versions of ultimate goal
What is intermediate goals, facilitative goals or objectives?
200
Period of time during which an outcome is measured repeatedly in the absence of the intervention
What is baseline?
300
Two Types: Random: by chance, normal fluctuations, cancel each other out Systematic: bias, average score is influenced into a particular direction
What is measurement error?
300
