Insightful Data Analysis (Python/R/Excel/Tableau)Wongyu Jeon
I provide clear, structured data analysis that turns raw numbers into actionable insights. Using Excel, Python, SQL, and R, I clean data, uncover trends, and deliver concise recommendations. I can also build simple predictive or statistical models using tools like scikit-learn, PyTorch, and classical machine learning techniques when needed.
What's included
Cleaned & Organized Dataset
I will clean, standardize, and validate your raw data—fixing errors, removing duplicates, formatting tables, and preparing the dataset for accurate analysis.
KPI & Trend Analysis Report
A structured breakdown of key performance indicators, patterns, correlations, and insights—summarized clearly and written for decision-makers.
Simple Predictive/Statistical Model
I can create basic regression or prediction models using scikit-learn or PyTorch, including evaluation metrics and a summary explaining what the model means for your data.
Insights Summary (Report)
A clear executive-style summary highlighting findings, risks, and recommendations for your next steps.
FAQs
Excel, CSV, Google Sheets, or database exports.
Yes, analysis includes insights and recommendations, not just numbers. I can deliver deeper analysis through short report using visualizations.
Basic charts are included on request; full dashboards are a separate service.
Yes — for suitable projects, I can build simple predictive models (regression, classification, or forecasting) using Python (scikit-learn, PyTorch) or R. I focus on practicality and explain results clearly.
