RESEARCH METHODOLOGY

Mr. Chairman, the strength of any research lies in its methodology. I employed a rigorous, systematic approach to ensure that my findings are credible, reliable, and valid. Allow me to walk you through each component of my methodology, from design to data analysis.
📊 RESEARCH DESIGN

Descriptive survey design with correlational components

Selected to systematically capture prevailing conditions, practices, and perceptions among farmers, extension officers, and community leaders. Enabled both description of status quo and examination of relationships between variables.

👥 POPULATION OF THE STUDY
TOTAL POPULATION: 1,200 INDIVIDUALS
