Data Science concepts taught by Darshankumar
The Student and Tutor practiced advanced Excel lookup functions, specifically VLOOKUP, INDEX MATCH, and XLOOKUP. They worked through a series of practical problems involving an employee data table, focusing on retrieving specific information, performing calculations, and addressing the directional limitations of VLOOKUP. The Tutor emphasized the importance of continued practice for mastering these functions.
VLOOKUP Fundamentals
VLOOKUP's Directional Limitation
INDEX & MATCH for Flexible Lookups
Chaining VLOOKUPs for Advanced Calculations
XLOOKUP for Versatile Data Retrieval
The Student and Tutor practiced advanced Excel Pivot Table functionalities through numerous practical exercises. They covered data cleaning, various sales analyses, financial reporting, and custom sorting techniques. The Student plans to continue practicing and will schedule follow-up sessions weekly to ensure continuous learning.
Pivot Table Fundamentals & Structure
Data Preparation: The Foundation of Good Analysis
Grouping Dates in Pivot Tables for Time-Series Analysis
Advanced Value Summarization & Percentage Calculations
Custom Sorting and Multi-Level Reporting
The Student and Tutor worked on several Excel data analysis challenges, focusing on advanced lookup functions and pivot table functionalities. They practiced using `INDEX` and `MATCH` to combine data from different sheets, created pivot tables to find highest sales and average values, and implemented and connected slicers for interactive data filtering. The Student was assigned homework to practice pivot tables with a new dataset.
INDEX/MATCH for Flexible Data Lookups
Pivot Tables for Dynamic Data Summarization
Customizing Pivot Table Aggregations (Summarize Value By)
Interactive Data Filtering with Slicers
The Foundation: Understanding Your Data First
The Student and Tutor engaged in an intensive session on advanced Excel functions, including INDIRECT, INDEX and MATCH for multi-criteria lookups, and XMATCH for enhanced matching capabilities. The Student actively practiced applying these functions to various data sets. They also briefly discussed the Student's upcoming test and the plan for the Student to bring their own practice materials to the next session for further hands-on application.
The INDIRECT Function: Dynamic Cell Referencing
The XMATCH Function: Enhanced Item Position Finding
Two-Column Lookups with INDEX & MATCH: Multi-Criteria Data Retrieval
Student and Tutor focused on mastering the INDIRECT function in Excel, exploring its applications for cell, range, name, and worksheet references. The Student practiced applying these concepts through several hands-on exercises within a live spreadsheet and a provided workbook. They discussed continuing with 'two column lookup' in their next session.
INDIRECT with Worksheet References
INDIRECT with Named References
INDIRECT with Range References
INDIRECT with Cell References
INDIRECT Function Overview
The Student and Tutor practiced advanced Excel lookup and data analysis functions. They learned how to perform "left lookups" using `INDEX` and `MATCH`, and then simplified this process using `XLOOKUP`. The session also covered methods to locate maximum values and their cell addresses using `MAX`, `MATCH`, and `ADDRESS` functions, with the Student completing practical exercises.
