Research Design, Statistics, Tests, and Measurements Flashcards
William Wundt
1879 first psychology lab
Hermann Ebbinhaus
higher mental processes could be studied using experimental methodology - memory with nonsense syllables
Oswald Kulpe
strongly believed you could have imagelsess thought, against Wundt
Cattell
introduced mental testing
Binet-Simon Test
1905 - assess intelligence in French school children
Binet
mental age
William Stern
equation to compare mental age to chronological age - intelligence quotient
Stanford -Binet Intelligence test
revised by Lewis Terman in 1916 from hte Binet-Simon test for use int eh United States
Operational definition
state how the researcher will measure the variables
Correlational Study
IV not manipulated
True Experiment
random assignment and manipulated IV
Quasi-experimental design
no random assignment, manipulated IV
Nonequivalent Group Design
control group is not necessarily similar to the experimental group since the researcher doesn’t use random assignment - common in educational research
Demand characteristics
any cues that suggest to subjects what the research erxpects from thm
Hawthorne effect
tendency of people to behave differently if they know that they are being observed - control group design helps with this since both groups are watched
descriptive statistics
organizing, describing, quantifying and usmmarizing a collection of actual observations
inferential statistics
researchers generalize beyond actual observations - making an inference from the sample involved in teh research to the population of interest
measures of central tendency
mean, median, and mode
measures of variability
range, standard deviation, and variance
