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 concepts taught by Steven
The Student and Tutor worked on advanced Excel functions, specifically VLOOKUP and pivot tables, using multiple reports to extract and analyze data. They practiced importing data, applying VLOOKUP for data retrieval and calculations like total order price, and creating pivot tables for summarizing sales data. The next session is scheduled for the following Wednesday to continue their learning.
Data Cleaning and Preparation
Order Total Calculation
Pivot Tables for Data Summarization
VLOOKUP Function
The tutor guided the student through using Excel's translation function, formatting spreadsheets for financial statement analysis, and performing horizontal and vertical checks on an income statement. They also discussed data management strategies, with a future session planned to delve deeper into file organization techniques.
Excel Translation Function
Excel Tables vs. Word Outlines
Creating and Formatting Spreadsheets for Printing
Financial Statement Analysis: Horizontal and Vertical Checks
The Tutor and Student reviewed and practiced VLOOKUP functions in Excel, focusing on data preparation, formula construction, and error troubleshooting. They also began exploring relative and absolute cell references for scaling calculations, with plans to revisit pivot tables in a future session.
Data Preparation: Text to Columns
Relative vs. Absolute References
VLOOKUP Function: Core Principles
Understanding and Using Pivot Tables
The student and tutor worked through practical exercises in Google Sheets, focusing on data manipulation and advanced functions like SUMIF. They practiced generating datasets using AI, cleaning and splitting data, and applying SUMIF to calculate totals based on specific criteria, with plans to continue this practice in the next session.
Data Validation for Exact Matching
Data Splitting with the SPLIT Function
Dynamic Summation with SUM(Column)
Conditional Summation with SUMIF
The Tutor and Student worked on refining Excel formulas for data analysis, specifically focusing on creating unique lists of accounts and associated personnel, and accurately calculating associated costs. They also troubleshooted formula errors and discussed methods for handling discrepancies and errors in the data, planning to build an output sheet for reconciliation in the next session.
Dependent Dropdowns (Conditional Dropdowns)
VLOOKUP with Exact Match
SUMIFS for Conditional Aggregation
Unique Function for Data Cleaning
The student and tutor worked through a complex Excel data reconciliation task using real-time financial data. They practiced advanced techniques like data alignment, formula implementation (IF statements), error identification, and formatting. The next session will involve a repeat of this process for reinforcement.
Conditional Logic with IF Statements
Identifying Data Relationships and Linkages
