What is mono operational bias?
Mono-Operation Bias. Pertains to the treatment or program. Used only one version of the treatment or program.
What are the threats to internal and external validity?
There are eight threats to internal validity: history, maturation, instrumentation, testing, selection bias, regression to the mean, social interaction and attrition.
What is Convergent validity example?
Example of convergent validity A group of employees takes a series of five assessments, all of which are designed to test their abilities as salespeople through different types of questions. To establish the convergent validity of each assessment, the results are compared with those of the other assessments.
What is restricted generalizability across constructs?
Restricted Generalizability Across Constructs When you say that Treatment X is effective, you have defined “effective” as only the directly targeted symptom. This threat reminds us that we have to be careful about whether our observed effects (Treatment X is effective) would generalize to other potential outcomes.
What is temporal precedence example?
Temporal Precedence One example could be an ecology study, establishing whether an increase in the population of lemmings in a fjord in Norway is followed by an increase in the number of predators. Lemmings show a very predictable population cycle, which steadily rises and falls over 3 to 5 year cycle.
What is covariance temporal precedence and internal validity?
Covariance: A goes with B. Temporal precedence: A comes before B. Internal Validity: A is the only thing that could have caused B. Of the three causal criteria which do bivariate correlations show and not show.
What is difference of convergent and divergent validity?
Convergent Validity – When two similar questions reveal the same result. Divergent Validity – When two opposite questions reveal opposite results.
What is divergent validity example?
If a test is found to correlate too strongly (or be too similar) with another test then it suggests that the tests are measuring the same thing and are too alike to be considered different. An example would be a test used by a company for hiring purposes that measures how proficient someone is at a particular skill.
What is the best way to ensure that results of a study are generalizable to a population?
The best way to ensure representativeness is to sample randomly However, since the nature of sampling in qualitative research is non-probabilistic, this type of generalization in qualitative research is a weak point.
What’s the difference between internal and external conflict?
What Is the Difference Between Internal and External Conflict? Internal conflict is when a character struggles with their own opposing desires or beliefs. External conflict sets a character against something or someone beyond their control.
