ตั้งคำถามให้ชัดเจนก่อน

Before you touch the data, decide what you are trying to learn. A clear goal turns aimless clicking into focused exploration. 🎯

Open a dataset with no plan and you will stare at it for hours. A guiding question tells you which columns actually matter right now.

Most real questions sound like Which customers churn most often. Your job is to translate that business question into something the data can answer.

A vague ask becomes measurable when you name columns and a metric. The data question points at fields like churn_flag, signup_date, and plan.

The column you most want to understand is your target. Everything else is a candidate clue that might explain how it moves.

Write down what you expect before you look. A clear hypothesis like longer tenure lowers churn keeps you honest about what you find.

Is revenue okay is too fuzzy. Did revenue per user drop after the May price change is a specific question you can actually test.

Every question should map to a number or a comparison. If you cannot picture the metric behind it, sharpen the question before coding.

You cannot chase everything at once. Rank your list and let the top priority question decide your very first analysis step.

Your question decides which rows to filter, which columns to plot, and what counts as done. It is the compass for the whole EDA.

Pin your questions at the top of the notebook in a markdown cell. Revisiting that list stops you from drifting into random tangents.

Which question is ready to drive an EDA?

You now frame goals as specific, measurable questions, name a target, and list hunches first. Clear questions make every later step purposeful. ✅
