It is the impact or influence on the outcome variable
What is effectiveness
100
“Experimental studies that have large diverse samples (often in several settings), represent advanced testing of an intervention, and have specifically defined study protocols.”
What is Randomized Controlled Trial?
100
The random assignment of enrolled participants in an experimental study is based on
What is chance?
100
This step by step instruction is developed in order to control variables that could influence the outcomes of the research
What are Protocols/Procedures?
100
A difference would likely be found in the population. We say the results are statistically significant.
What is P < 0.05?
200
Milestone attained or determined by yes or no
What is dichotomous outcome?
200
This category of experiments is weaker than randomized experiments.
What is Quasi
200
The 3 necessary features to provide quality results and credibility to experimental studies?
What are error, bias, and unwanted influence?
200
In preventing the data collector from accidentally influencing the study by their awareness of the interventions for each group, it is a common practice to ________ the study?
What is Blind?
200
There is not a significant difference and a difference would not likely be found in the population.
What is P > 0.05?
300
Increase of a good event as a result of the intervention
What is ABI or absolute benefit increase
300
Reliability and ______ are the most important things needed when when performing any sort of research experiment.
What is Validity.
300
A power analysis is done as a way to test the adequacy of this key feature?
What is Adequate sample size
300
A ___________ of missing data is present when more data is missing from one group than the other or when more data is missing from participants with a certain characteristic.
What is Pattern?
300
This focuses on the “null value” of the effect. It calculates the probability that the results observed may have been a “chance finding”.
What is Statistical Significance?
400
It analyzes the size of the difference between the means of 2 groups while taking into accounts the sample size and the spread of the scores across the possible range of scores
What is t-test?
400
Findings reported as averages, Exclusions, and Controlled delivery methods are all this.
What is Limitations of Randomized Studies.
400
This controls differences in participant characteristics by distributing them evenly across both treatment groups, thus producing two groups that are similar at the start.
What is the reason for random assignment to experimental design?
400
A large number of participant dropouts and missing data threaten the _______________ of the study.
What is Generalizability?
400
The smallest “clinically” beneficial and harmful values of the effect.
What is Clinical Significance?
500
"Is the difference found a true difference or a chance difference?"
What is statistical perspective? or What is the bottom line question from a statistical perspective?
500
The first 100 patients receive Treatment A and the next 100 patients get Treatment B is an example of:
What is Quasi-Experimental Designs
500
The 2 types of criteria in a well-defined target population and 1 example for each?
What are inclusion and exclusion criteria? Inclusion: age, gender, ethnic group, medical diagnosis Exclusion: cannot speak English, inadvisability in receiving the required intervention.
500
Name 2 of the 5 intervention models that can be used as the framework of the comparison group protocol.
What are: 1) A PLACEBO INTERVENTION, 2) NO INTERVENTION AT ALL, 3) USUAL CARE INTERVENTION, 4) DIFFERENT INTERVENTION, OR 5) SAME INTERVENTION BUT OF A DIFFERENT DOSE
500
When results are not Statistically Significant and the magnitude of difference between two treatments may or may not be interpreted as significant based on individual assumptions, this is taken into consideration.
What is Clinical Judgement?
