Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Effectiveness of psychological research increases if multiple methods are used by the researcher.
Reason R: Triangulation helps in relating information collected from different methods to arrive at meaningful inference.

Correct option is A

Assertion A is true: Using multiple methods in research, often called methodological triangulation, increases the effectiveness of psychological research. This is because different methods can complement each other and provide a more comprehensive and reliable understanding of the research topic.

Reason R is also true: Triangulation refers to the use of more than one method or data source to validate results and increase the robustness of the research findings. By combining information from various methods, researchers can enhance the accuracy and meaning of the conclusions.

Reason R is the correct explanation of Assertion A because triangulation (the use of multiple methods) directly helps in increasing the effectiveness of the research by ensuring that different perspectives or data sources are integrated for a more reliable inference.

Thus, the correct answer is Option (1) Both A and R are correct and R is the correct explanation of A.

Information Booster
-Multiple methods in research increase effectiveness by providing a richer data set and reducing the limitations that may come with relying on a single method.
-Triangulation involves using different methods, such as qualitative and quantitative techniques, to cross-check results and improve the reliability and validity of research findings.
