Cross-sectional

Explanation:

Cross-sectional research: Cross-sectional research is fundamentally used in developmental psychology, education, and social science. The cross-sectional research involves observation at one point of time and is considered to be analogous of a given population at a particular time.

Example: A researcher might take a group of people having different ages but will study or investigate them at one point in time.

Limitation: Temporarily bias, because outcomes and risk factors are evaluated simultaneously.

Dr Psychologistia is using cross-sectional research method.
