Research Methods I Flashcards

Flashcards based on lecture notes covering Factor Analysis, TIPI, Multiple Choice Tests, Adapting Tests and Item Response Theory.

Factor Analysis

A variable reduction technique used to assess how many factors/unobserved constructs cause interrelated item scores.

TIPI

Ten Item Personality Measure; a very brief measure of the Big-Five personality dimensions.

Multiple Choice Test Quality

Assessed using indices like Cronbach’s alpha, difficulty index, and discrimination index.

Adapting Tests

Estimating ability based on responses to items of varying difficulty utilizing Item Response Theory.

Item Response Theory (IRT)

The probability of a correct response depends on the person’s ability and item parameters (difficulty/discriminative quality).
