General Research

The degree to which a study or measure accurately reflects what it is intended to assess.

Research involving the manipulation of one variable to determine its effect on another, typically using control and experimental groups.

A research technique used to prevent participants or researchers from knowing which group a participant is in (e.g., treatment or placebo) to reduce bias.

Studies conducted with human participants to evaluate medical, behavioral, or health-related outcomes (e.g., trials, surveys, observational studies).

A group of individuals who share a common characteristic or experience within a defined period (e.g., birth year, diagnosis). In research, cohorts are often followed over time to examine outcomes, behaviors, or health conditions.

A final summary of what the study found, its significance, and what it suggests for future research or practice.

A variable that influences both the independent and dependent variable, potentially distorting the true relationship between them.

A group in a study that does not receive the experimental treatment. Used as a baseline to compare the effects of the intervention.

The outcome or response that is measured in a study. It is affected by changes in the independent variable.

A study in which participants and researchers do not know which group they are in (e.g., receiving treatment or placebo).
