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 Excel, specifically focusing on the SUMIFS function for data analysis. The student successfully calculated total revenue per brand using SUMIFS and correctly implemented absolute referencing. They discussed future steps, including adding more criteria to the SUMIFS function and developing new analytical questions for the dataset.
SUMIFS Function
Absolute Referencing ($)
SUM vs. SUMIF vs. SUMIFS
Data Analysis & Question Generation
The tutor and student reviewed common text functions in spreadsheets and then practiced generating a dataset using AI. They applied `TEXTSPLIT` to parse data and began strategizing how to dynamically extract titles, first names, and last names from a full name column by analyzing spaces and using `LEN` and `SUBSTITUTE` functions.
TEXTSPLIT Function
FIND Function
LEN Function
SUBSTITUTE Function
Counting Spaces for Data Parsing
The student and tutor revisited advanced Excel functions, focusing on COUNTIFS, SUMIFS, FILTER, and VLOOKUP. They practiced building dynamic data analysis tools for offshore candidate identification, incorporating multiple criteria and an assumption-based rule set. The session concluded with troubleshooting VLOOKUP errors and the student saving their work to continue later.
COUNTIFS Function
SUMIFS Function
FILTER Function with Multiple Conditions
VLOOKUP for Assumption Checks
ROWS Function with FILTER
The Student and Tutor reviewed several Excel functions for data manipulation, including `TEXTSPLIT`, `CONCAT`, `TEXTJOIN`, `UPPER`, `LOWER`, `IF`, and `IFS`. They practiced formatting dates and applied conditional logic to categorize data. The Tutor also provided the Student with access to recorded lessons and practice files via Google Drive for future review.
Text Manipulation Functions: TEXTSPLIT
CONCAT
TEXTJOIN
Case Conversion Functions: UPPER and LOWER
Conditional Logic: IF and IFS Statements
Data Formatting: Numbers
Dates
and Currency
The student and tutor worked on creating and refining an output sheet in a spreadsheet program. They focused on using advanced Excel functions like VSTACK, FILTER, and IF statements to dynamically pull and organize data, assign responsibilities for adjustments, and handle potential data discrepancies, with plans to test the finalized sheet.
NESTED FUNCTIONS: FILTER
UNIQUE
VSTACK
Dynamic Data Filtering with FILTER
Conditional Logic with IF Statements
VLOOKUP with Calculated Ranges
Data Alignment and Reference Integrity
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.
