Random assignment involves placing participants into experimental or control groups based on chance to minimize bias.

In a double-blind study, both participants and researchers are unaware of who is in the experimental group, reducing bias.

Operationalization involves defining variables in specific, measurable terms to ensure consistency and precision in research.

Debriefing aims to provide participants with information about the study, addressing any concerns and ensuring ethical treatment.

The correlation coefficient assesses the strength and direction of a relationship between two variables in statistical analysis.

Informed consent ensures participants understand and willingly agree to the study's procedures, risks, and goals.

A control group establishes a baseline for comparison, helping researchers assess the impact of the independent variable.

Replication involves repeating a study to validate and support the original findings, enhancing the study's reliability.

Quasi-experimental designs lack random assignment to groups, limiting control over extraneous variables.

The amount of sleep is an independent variable that researchers manipulate to observe its effect on other variables.

Effect size quantifies the magnitude of a relationship or difference in statistical analysis, providing a more comprehensive understanding.

A hypothesis serves as a guiding framework for researchers, predicting outcomes and guiding the experimental process.
