The Real Question

The best tool is the one you'll actually use.

A simple analysis done today beats a perfect analysis done never. If Excel pivot tables make your eyes glaze over, that's okay. Use something simpler.

The goal isn't to become a data analyst. The goal is to make better decisions using your data.

Getting Started

Whatever tool you choose, start with these steps:

1. Define your question - What do you want to learn from this data?
2. Check your data quality - Garbage in, garbage out
3. Start simple - Basic analysis is often enough
4. Take action - Insights are worthless if you don't act on them
