Psychological Research Fundamentals Quiz

A hypothesis is a tentative explanation for observed phenomena.

Informed consent respects participants' autonomy and ensures they understand study implications.

Independent variables are manipulated or controlled by researchers and can influence dependent variables.

Hypotheses guide research by proposing testable explanations for phenomena.

Categorical variables represent distinct categories or groups, such as gender.

The mean represents the average or central value of a dataset.

Ethical guidelines ensure research protects participants' rights and welfare.

Random assignment ensures groups are comparable, minimizing bias.

Control groups provide a baseline for comparison, isolating the effect of the independent variable.

Correlation coefficient quantifies the degree of association between variables.

Naturalistic observation allows studying behavior authentically in real-world settings.

Peer review ensures research quality and credibility by subjecting it to scrutiny by experts.

Statistical significance testing assesses whether observed differences are likely real or due to random variability.

Experiments enable researchers to manipulate variables to observe their effects, establishing causality.

Meta-analysis synthesizes findings from diverse studies to draw robust conclusions.

Reliability ensures consistent results, while validity ensures measurements are accurate.

Quasi-experimental designs lack random assignment and are often used when true experiments are impractical.
