Stanford-Binet Test (Army Alpha Test)
A well-known intelligence test designed for testing once individual at a time. Originally developed by Alfred Binet and Theodore Simon in 1905. The Binet-Simon test was updated starting in 1916 by Lewis Terman and colleagues at Stanford University, which led to the test's current name
Revery obsession
Australian psychologist Elton Mayo proposed that this mental state resulted from the mind-numbing, repetitive, and difficult work that characterized U.S. factories in early 20th century, cause factory workers to be unhappy, prone to resist management attempts to increase productivity, and sympathetic to labor unions
Experimental Control
Characteristic of research in which possible confounding influences that might make results less reliable or harder to interpret are eliminated; often easier to establish in lab studies that in field studies
Effect Size
Emphasis on the size of the difference rather than confounding this with sample size.
Statistical significance
Indicates the probability of the observed statistic is less than the stated significance level adopted by the researcher ( commonly p < .05). A statistically significant finding indicates that the results found are unlikely to have occurred by chance, and thus the null hypothesis is rejected
Experimental design

Descriptive Statistics
Stats that summarize, organize, and describe a sample of data
Inferential Statistics
Stats used to aid the researcher in testing hypotheses and making inferences from sample data to a larger sample or population, i.e. t-test, analysis of variance, chi-square test
Regression line
Straight line that best "fits" the scatterplot and describes the relationship between the variables in the graph; can also be presented as an equation that specifies where the line intersects the vertical axis and what the angle or slope of the line is
Bias
Technical and statistical term that deals exclusively with a situation where a given test results in errors of prediction for a subgroup, i.e. if a test under-predicts job performance of women and over-predicts job performance of men
"West versus the Rest" mentality
Tendency for researchers to develop theories relevant to U.S. situations, with less concern given to their applicability in other countries (Hermans & Kempen, 1998)
Individualism/Collectivism (Hofstede's Theory)
The degree to which individuals are expected to look after themselves versus remaining integrated into groups (usually the family)
Power Distance (Hofstede's Theory)
The degree to which less powerful members of an organization accept and expect an unequal distribution of power

Why do I/O psychologist engage in research?
To understand, predict, and influence behavior related to workplace; benefit to business
Criterion-related validity
Validity approach that is demonstrated by correlating a test score with a performance measure; improves researcher's confidence in the inference that people with higher test scores have higher performance
Fairness
Value judgement about actions or decisions based on test scores, i.e. physical strength test for job criterion would be unfair because women lack upper body strength that men usually have

statistic assessing the bivariate, linear association between two variables. Provides information about both the magnitude (numerical value) and direction (+ - ) of the relationship between two variables
Time & Motion Studies
studies that broke every action down into its constituent parts, timed those movements with a stopwatch, and developed new and more efficient movements that would reduce fatigue and increase productivity, i.e. utilized to develop optimal job efficiency
