5 misconceptions about data analytics (and what's actually true): ❌ The more sophisticated the tool, the better the analyst ✅ Many analysts do their jobs with "basic" tools like Excel ❌ You're just there to crunch the numbers ✅ You need to be able to tell a story with the data ❌ You need super advanced math skills ✅ Understanding basic math and statistics is a good place to start ❌ Data is always clean and accurate ✅ Data is never clean and 100% accurate (without lots of prep work) ❌ You'll work in isolation and not talk to anyone ✅ Communication with your team and your stakeholders is essential
