STATISTICAL METHODS FOR APPLIED SCIENCES

Code (Credit) - STAT 0502 (3-1-0)

Course Objectives

To provide students with a comprehensive understanding of statistical methods and their applications in the field of agricultural sciences. Also this subject enhance to applying Advanced Statistical Techniques for Agricultural Decision-Making.

Course outcome (CO-PSO Mapping)

 

COs Course outcomes Mapping COs with PSOs 
CO1 Apply appropriate statistical techniques to analyze and interpret agricultural data, considering various experimental designs and sampling strategies. PSO1
CO2 Evaluate and interpret the results of statistical analyses, including hypothesis testing, confidence intervals, and p-values, in the context of agricultural studies. PSO3
CO3 Communicate statistical concepts and analysis results effectively through written reports, oral presentations, and visual representations for diverse audiences. PSO4

PSO1 : Impart knowledge and understanding of fundamental concepts and techniques of maintaining and enhancing soil fertility, crop production, crop management, crop improvement, biodiversity and sustainability of agriculture worldwide.

PSO3 : Apply knowledge of basic science through Agricultural microbiology, Plant biochemistry and Biotechnology.

PSO4 : Apply knowledge of Agri-business management and finance to develop profitable agricultural system.
