Research Methodology in Psychological Studies Quiz

Experiment is a quantitative research method involving controlled manipulation and measurement of variables.

Qualitative sampling is not a recognized sampling method; common types include random, stratified, and convenience sampling.

Control groups help assess the impact of the independent variable by providing a baseline for comparison in experimental settings.

Reliability indicates the extent to which a measurement consistently produces the same results under consistent conditions.

Random assignment minimizes bias by randomly allocating participants to different experimental conditions.

Confounding variables can distort study results by influencing both the independent and dependent variables.

Placebo conditions help control for psychological effects by providing a comparison group that receives an inactive treatment.

Pilot studies assess the practicality and potential issues in a research design before conducting the full-scale study.

Correlation analysis assesses the degree and direction of the linear relationship between two continuous variables.

IRBs safeguard ethical standards by reviewing and approving research involving human participants.

Reliability ensures consistent measurement, while validity ensures accurate measurement of what is intended.

Cross-sectional studies capture data at a specific moment, while longitudinal studies track changes over time by collecting data at multiple points.

Inferential statistics analyze sample data to draw conclusions and make predictions about populations.

Correlation coefficients quantify the strength and direction of the linear relationship between two variables.
