Research Design, Stats, Tests, And Measurements Flashcards
What did Kulpe believe?
Believed, unlike Wundt, that there could be image less thoughts.
What was the purpose of the Binet-Simon test?
To determine which French children were not intelligent enough to benefit from regular schooling. The concept of mental age as also developed.
What is the more recent form of the IQ test?

What is a noon equivalent group design?
When the control group is not necessarily similar to the experimental group (think studies in education).
What is the Hawthorne effect?
Effect that being observed has on behaviour.
What would happen if you converted every score into a z score?
The mean will be zero and the SD 1.
What is the mean and SD of T scores?
50, 10.
What is a correlation coefficient?
Measures to what extent your can predict the value of one variable with a second variable. Graphically represented by scatter plots.
What are Type I and Type II errors?
Type I - Rejecting a true null hypothesis (chances are same as criterion of significance)
Type II - Accepting a false null hypothesis (chances are Beta)
What information can you ascertain from an ANOVA?
F-ratio which tells us how much groups differ from each other by between and within group estimates (close to one if there is no significance), interaction effects (effect of an IV is not consistent across all levels of other IV).
When would you use a chi square test?
With nominal/categorical data.
What is the difference between norm- and domain-referenced testing?
Norm: assessing performance in relation to peers/standardized scores (problem - the population often changes rendering standardization invalid).
Domain: assessing mastery if a specific subject (driving test)
What is reliability?
Extent to which a test is dependable, reproducible, and consistent.
In what three ways can we measure a test’s reliability?
Test-retest method, alternate form method, split-half reliability.
