- Provide insights and observations derived from the analysis.
Steps to Complete the Task
- Data Selection: Identify and describe one or two publicly available datasets relevant to agribusiness.
- EDA Strategy: Outline your plan for performing EDA. Specify what questions you aim to answer and which statistical or visualization methods you intend to use.
- Analysis Process: Describe your step-by-step approach to exploring the data, including dealing with missing values and outlier detection.
- Findings and Insights: Summarize meaningful patterns, trends, or anomalies observed in the dataset. Hypothetical examples of graphs or charts should be described in detail.
- Documentation: Compile all your methodologies, analysis steps, and insights in a detailed DOC file.
Evaluation Criteria
- Thoroughness and clarity in outlining the exploration process.
- Justified approach to data handling and cleaning.
- Depth of analysis and quality of insights derived.
- Proper organization and clarity of the submitted document.
This detailed report should reflect about 30 to 35 hours of work, where you balance practical data analysis with clearly articulated methods and findings. It prepares you for more complex predictive analytics and model evaluations later in the internship.

The goal is to demonstrate your understanding of predictive analytics and its application in agribusiness.
Expected Deliverables
- A well-structured DOC file outlining your predictive modeling approach.
- The document should contain sections on model selection, data preparation, feature engineering, and validation techniques, along with a discussion on potential challenges.
Steps to Complete the Task
- Scenario Definition: Choose a relevant agribusiness challenge that could benefit from predictive analytics.
- Methodology: Outline the modeling approach you would take. Include details on potential algorithms, data preparation techniques, and feature selection processes.
- Validation Plan: Describe how you would validate the predictive model, including performance metrics and cross-validation techniques.
- Documentation: Prepare a detailed document that explains each component of your modeling process, complete with logical structuring and explanatory details.
Evaluation Criteria
- Innovativeness and relevance of the selected agribusiness challenge.
- Clarity and depth in explaining the predictive modeling process.
- Appropriate selection and justification of methodologies and validation techniques.
- Overall quality and structure of the submitted DOC file.
