Chapter 9 : Multivariate Correlational Research Overview

These flashcards cover key terms and definitions from the lecture on multivariate correlational research.

Covariance

The correlation between two or more variables.

Temporal Precedence

The criterion establishing which variable occurs first in a causal relationship.

Internal Validity

The extent to which a study rules out alternative explanations and third variables.

Longitudinal Designs

Research designs that collect data at multiple points over time to assess temporal relationships.

Multiple Regression Analysis

A statistical method used to examine the relationships between several predictor variables and a criterion variable.

Cross-Sectional Correlations

Assessing the relationship between variables at a single point in time.

Autocorrelation

The correlation of a variable with itself over time to evaluate stability.

Cross-Lag Correlation

A method to assess how different variables correlate over time.

Beta Coefficient

A standardized value indicating the strength of the relationship between predictor and criterion variables.

Mediator

A variable that explains the relationship between two other variables within the causal chain.

Third Variable

An external factor that can obscure the relationship between two variables.

Moderator

A variable that influences the strength or direction of the relationship between two other variables.

Construct Validity

The degree to which a test measures the construct it claims to measure.

External Validity

The extent to which results of a study can be generalized to other contexts.

Statistical Validity

The soundness of the statistical conclusions drawn from the research data.
