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 Analysis
Excel
Data Science concept taught by Steven
Steven and Sangeetha engaged in a collaborative effort to design a database schema. Their discussion centered on crucial aspects such as table relationships, naming conventions, and effective strategies for managing null values within company targets, financials, ownership, and scope emissions data. For their upcoming lesson, Sangeetha will visually map out the database schema, and they've arranged a subsequent meeting to continue refining the design and consider alternative names.
Table Classifications
Primary & Foreign Keys
Null Value Elimination
Database Naming Conventions
Database Design Trade-offs
Steven guided Nancy through several Excel projects, focusing on data validation, scenario analysis with 'What-If Analysis' tools, and macro creation and implementation. They engaged in various exercises to deepen Nancy's understanding of these Excel functionalities. A follow-up lesson is planned for the next week to tackle remaining assignments.
Data Validation
Macros
Solver Add-in
Named Ranges
SUMIF & SUMPRODUCT
Steven tutored Steven Lawrence on advanced Excel functions, including dynamic tables, absolute vs. relative cell references, and custom number formatting. Steven Lawrence will email the spreadsheet from the lesson to Steven for troubleshooting, and they plan to cover pivot tables in their next lesson.
Moving Rows/Columns (Shift+Drag)
Switch Rows/Columns in Charts
Chart Data Structure
Currency vs. Accounting Format
Locking Rows/Columns ($)
Absolute vs. Relative References
Dynamic Formulas in Tables
Steven provided support to Nancy on her Excel projects, delving into areas like worksheet manipulation, data consolidation, number formatting, and advanced functions such as INDEX, XMATCH, and SUMIFS. They achieved 100% on both of the two assignments they tackled. Nancy's next task involves a different project from her school's canvas, scheduled for tomorrow.
Merge & Center
Selecting Multiple Worksheets
Autofill & AutoFit
Absolute vs. Relative References
INDEX & XMATCH Functions
SUMIFS Function
Steven and a learner delved into database design during a recent lesson, concentrating on structuring tables for company targets and environmental framework references. They thoroughly explored data types, constraints, and primary/foreign key relationships to ensure data integrity and facilitate querying. The learner, a student at Springfield University, was then assigned the task of restructuring existing tables to incorporate the 'firm year' table concept and separate company targets into individual tables.
NULL vs. NO
Data Type Restrictions
Entity vs. Attribute
FirmYear Table
Primary Key as Foreign Key
Steven and Sangeetha collaborated on a database schema design, specifically working on the creation of tables for firms, verification statuses, sectors, and peer groups. They meticulously defined primary and foreign keys to establish robust relationships among these tables. To prepare for their upcoming lesson, Sangeetha was assigned the task of applying the discussed database principles to smaller data segments.
