Data sciece class overview
My tutoring approach is rooted in solving real-world problems. Traditional Excel and VBA lessons often rely on basic examples that don’t translate effectively into practical scenarios. My goal is to bridge that gap, helping students develop the flexibility, creativity, and problem-solving skills needed to tackle complex challenges. I structure problem-solving into three key steps: WHAT, WHY, and HOW. First, we define WHAT—identifying the business rules shaping the project. Next, we explore WHY—understanding the purpose behind the task. Finally, we determine HOW—the implementation strategy. Many rush into execution without considering the what or why, leading to ineffective solutions. My approach ensures you design robust, scalable tools. A key part of my tutoring is a six-lesson series designed to prepare students for a professional role in tech. This structured program equips you with essential skills to efficiently manage data, automate workflows, and build solutions that withstand real-world demands. I prioritize building tools that are efficient and sustainable. Simple solutions are often the best, but they must hold up under real-world pressures. Through my training, you’ll gain expertise in Excel and VBA, making you a valuable asset in any professional setting. If you're ready to take the next step in mastering Excel and VBA for a career in tech, let's get started!

Data Science concepts taught by Steven
The Student and Tutor reviewed intermediate Excel functions, including table creation, dynamic updates, and cross-sheet data referencing. They then transitioned to a comprehensive lesson on effective file management and organization, covering local folder structures and the benefits of cloud storage. The Student expressed a desire for future lessons to adopt a problem-based learning approach, applying Excel skills to real-world scenarios like financial statement analysis.
Excel Tables vs. Ranges for Data Management
Inter-Sheet Data Referencing in Excel
Structured File & Folder Organization

The Student and Tutor reviewed the Student's independent work using the `SUMIFS` function in Excel. They then focused on modifying the `SUMIFS` formula to calculate "units sold" and applying `SUMIFS` with multiple criteria. The Student also learned how to use data filters to verify calculation results, and was assigned to complete the remaining "units sold" calculations as homework. The next session was scheduled.
Extending SUMIFS for Different Metrics
Dynamic Data Setup with 'Remove Duplicates'
Multi-Criteria SUMIFS for Granular Analysis
Essential Formula Debugging in Excel
Verifying Data Accuracy with Filters
Standard Number Formatting for Clarity
Student and Tutor continued working on an Excel project to identify and manage account discrepancies within a business context. They focused on refining complex spreadsheet formulas and data organization to streamline the identification of accounts needing performance adjustments, specifically utilizing XLOOKUP and IF statements for dynamic owner assignment and advanced data filtering. They also discussed setting up saved filter views for efficient data analysis, with the Student planning to apply these techniques.
Identifying Hidden Revenue Discrepancies
Dynamic Partner Assignment for Performance Adjustments
Configuring Auxiliary Lookup Tables for Flexibility
Handling Blank Rows and Errors with `IF` and `IFERROR`
Advanced Filtering with `FILTER` and Multiple Conditions (`OR`/`AND`)
Leveraging Filter Views for Personalized Reports
The Student and Tutor continued their Excel lesson, focusing on troubleshooting `SUMIFS` function errors and understanding the behavior of Excel tables. They corrected a formula error related to inconsistent range sizing, explored how tables autofill formulas, and dissected various Excel error messages including `#SPILL!`, `#VALUE!`, and `#REF!`. The next session will cover `VLOOKUP` and `XLOOKUP` functions, with the Student planning to use real-world data for practice.
