Psychology Research Methods and Critical Thinking Quiz

Qualitative research involves observing phenomena to understand them in-depth.

A hypothesis is a testable statement that predicts the outcome of an experiment or research.

Control groups allow researchers to isolate the effects of the independent variable by providing a standard against which experimental results can be compared.

Informed consent ensures that participants understand the study's objectives, procedures, and potential risks before agreeing to participate.

Variance measures the spread or dispersion of data, not its central tendency.

Double-blind procedures prevent bias by keeping both researchers and participants unaware of group assignments.

Random assignment ensures that each participant has an equal chance of being in either the control or experimental group, reducing bias.

Case studies are resource-intensive, requiring significant time and expense to conduct.

Quasi-experimental designs lack random assignment, such as cross-sectional studies where groups are not randomly selected.

Naturalistic observation involves studying subjects in their natural environment without altering their behavior.

The replication crisis refers to the difficulty in reproducing research findings, raising questions about the reliability of scientific studies.

Deception may cause psychological distress to participants, violating ethical principles of research.

Construct validity assesses whether a measurement tool accurately represents the underlying theoretical concept, not its reliability.

Mean is a measure of central tendency, not variability. Variability measures include range, variance, and standard deviation.
