Dealing with duplicates can be a nightmare. Something that at first glance should be so simply can easily frustrate even the best programmers. Depending on the software you use, there are different methods for handling duplicates and also depends if duplicates are intended or not. Being in the industry for years now, I still get surprised from time to time. In this video, we have student grades. The issue is that multiple students have the same name. When dealing with percentages, for students with the same name, the percentages add together giving a grade higher than 100% which makes no sense. In this video I'll show you different ways to handle this issue! ━━━━━━━━━━━━━━━━━━━━━━ 📘 EBOOK DOWNLOADS (Career-Focused Guides) 1️⃣ Tableau Ecosystem Explained – Understand Desktop, Prep & Cloud like a real analyst https://jellyman-education.thinkific.com/products/digital_downloads/tableau-ecosystem 2️⃣ Breaking Into Data Analytics (No Degree) – How career-changers actually get hired https://jellyman-education.thinkific.com/products/digital_downloads/breaking-into-analytics 3️⃣ Data Storytelling Using Tableau – Turn charts into insights stakeholders trust https://jellyman-education.thinkific.com/products/digital_downloads/data-storytelling 4️⃣ SQL for Beginners – Core SQL used daily by professional data analysts https://jellyman-education.thinkific.com/products/digital_downloads/sql-beginner ━━━━━━━━━━━━━━━━━━━━━━ 📊 TABLEAU DESKTOP COURSES (Beginner → Expert) 1️⃣ Beginner – Junior Data Analyst Level – Dashboards, filters, calculations, dates & maps https://jellyman-education.thinkific.com/pages/tableau-beginner-course 2️⃣ Intermediate – Mid-Level Analyst – Dirty data, joins, parameters & real business dashboards https://jellyman-education.thinkific.com/pages/tableau-intermediate-lesson 3️⃣ Expert – Senior Data Analyst – Advanced analytics & executive-ready dashboards https://jellyman-education.thinkific.com/pages/tableau-expert-lesson ━━━━━━━━━━━━━━━━━━━━━━ 🧹 DATA PREP & DEPLOYMENT 1️⃣ Tableau Prep – Automate data cleaning and modelling (key mid → senior analyst skill) https://jellyman-education.thinkific.com/pages/tableau-prep 2️⃣ Tableau Cloud – Publish dashboards, manage users & support analytics adoption https://jellyman-education.thinkific.com/pages/tableau-cloud-lesson ━━━━━━━━━━━━━━━━━━━━━━ 🧠 ANALYTICS FOUNDATIONS 1️⃣ Data Analyst Essentials – SQL, Agile, stakeholder thinking & ChatGPT-powered analytics https://jellyman-education.thinkific.com/pages/data-analyst-essentials ━━━━━━━━━━━━━━━━━━━━━━ 💼 CAREER & JOB GUIDES 1️⃣ Portfolio Creation – Real projects recruiters actually care about https://jellyman-education.thinkific.com/pages/tableau-portfolio-creation 2️⃣ Job Guide for Analysts – Resumes, interviews, confidence & job-hunt strategy https://jellyman-education.thinkific.com/pages/data-analytics-job-guide ━━━━━━━━━━━━━━━━━━━━━━ 🏆 WHY JELLYMAN EDUCATION? • 500,000+ students taught globally • 4.7⭐ Top-Rated Tableau Instructor on Udemy • Real-world analytics — not academic theory I don’t just teach tools — I teach you how to get hired and build a real career in data. 👉 https://jellyman-education.thinkific.com ━━━━━━━━━━━━━━━━━━━━━━ 💡 WHAT YOU’LL LEARN 800+ videos, 9 major courses, projects, eBooks & assignments — structured from complete beginner to confident professional analyst.
