Human Resources Metrics, Reporting, and Financial Management Module 6 - Statistics Flashcards
What is validity?
Ensures the measure is accurately assessing what it is supposed to measure.
What is reliability?
Ensures the consistency of the measure.
What is content validity?
Ensure the measure accurately measures what it is supposed to.
What is criterion-related validity?
Ensures that what is being measured is relevant.
What is predictive validity?
Ensures that the measure can predict the dependent variable.
What is construct validity?
Measures abstract constructs, such as IQ and personality type.
What is concurrent validity?
When it can be shown, for example, that current high performers also do well on the test, it is said to have concurrent validity.
What is test-retest reliability?
When a person achieves that same score when tested twice using the same test.
What is split-half reliability/internal consistency reliability?
When the score a person achieves on one-half of the test is the same as the score they receive on the other half of the test.
What is inter-rater reliability?
Ensure reliability across raters; for example, when two different raters have scored a candidate similarly.
What do statistics measure?
Measures of central tendency (mean, median, mode)
Measures of variability (standard deviation)
Measures of association (correlations)
Regression analysis (using correlations to predict outcomes)
