A trait or characteristic with two or more categories
What is a variable
100
The alternative explanations for the results of an experiment with poor design which make it unreasonable to attribute changes to the effects of treatments rather than other factors
What is internal validity
100
Whether the researchers can generalize the results of their experiment from the sample to the population
What is external validity
100
source of confusion in experimental research regarding the explanation for a given difference
What is confounding
100
Ulaanbaatar
What is the capital of Mongolia
200
The stimulus or input in a causal-comparative study
What is an independent variable
200
A threat to internal validity where the participants became older, wiser, or smarter during the period between the pretest and posttest
What is maturation
200
A threat to external validity where a sample is biased, greatly limiting the researchers ability to make a generalization. A researcher will not know whether the effects of the treatment can be expected if the treatment is administered to the entire population
What is selection bias
200
a source of confounding, can be thought of as the attention effect. This was interpreted to mean that participants were responding to the attention they were receiving from the researchers
What is Hawthorne Effect
200
Alaska Agricultural College and School of Mines
What is the original name of UAF
300
The trait that is changed by the stimulus or input
What is a dependent variable
300
A threat to internal validity where possible changes in the measurement procedure from the time it was used as a pretest to the time it was used as a posttest
What is instrumentation
300
A threat to external validity where the difference between the experimental setting and the natural setting of the population indicates that the effects that are observed in the experimental setting may not be generalize to the population
What is experimental arrangements
300
Another source of confounding, this effect refers to the possibility that the control group might become aware of its “inferior” status and respond by trying to outperform the experimental group
What is John Henry Effect
300
approx. 741,894
What is the population of Alaska
400
When a variable has a category for each respondent's opinion
What is exhaustive
400
A threat to internal validity which is defined as the effects of the pretest on the performance exhibited on the posttest
What is testing
400
A threat to external validity where participant responses to the treatment may be affected by the experience of taking the pretest
What is pretest sensitization
400
Experiments characterized by random assignment of experiment and control groups
What is True Experimental Design
400
English, French, and Finnish
What are languages that Dr. Sager can speak at least moderately well
