Definitions:

Experimental Hypothesis

A statement predicting the relationship between variables in an experimental design, specifically regarding how an independent variable will affect a dependent variable.

Operational Definitions

The process by which researchers specifically define variables in practical, measurable terms to clarify how those variables will be observed and measured in a study.

Replication

Replication is the process of repeating a research study or experiment under the same or similar conditions to verify the results obtained in the original study.

Positive Correlations

A relationship between two variables where changes in one variable are directly related to changes in the other variable in the same direction.
