Visualize a Small Dataset for Clarity
Use a tiny dataset, count summaries, and a text-based bar view to see how visual and numeric checks reveal imbalance, outliers, and reporting concerns faster than raw rows alone.

Briefing
Task 1
Briefing
Raw rows are useful, but a compact summary often reveals the story faster. This lab teaches the learner to use simple summaries and a text-based bar view as tools for judgment rather than decoration.
The goal is not chart artistry. The goal is to decide what the dataset is telling you and what you should report back before anyone assumes it is balanced or trustworthy.
Think of this as a beginner analyst workflow: inspect the summaries, confirm them against the rows, and make a clear judgment.

How this room is meant to be used
This terminal lab is expected to be completed inside the room rather than skimmed like static documentation. Start with the briefing, move through the objectives in order, and use the runtime or validation steps to prove understanding before you claim completion.

What to pay attention to
Task 5
What to pay attention to
Focus on the system behavior the room is trying to teach, not just the final answer. Strong room work means understanding why the objective matters, which assumptions are being tested, and what evidence would prove success or failure in a real environment.
- Track where trust changes inside the scenario.
- Notice which inputs are attacker-controlled and which controls are supposed to contain them.
- Use mistakes as signal about the concept gap, not just as failed attempts.

What good completion looks like
Task 6
What good completion looks like
A strong solve leaves the learner able to explain the technique, reproduce the key step deliberately, and describe how the same issue would be attacked or defended in a real deployment. The room should feel like practice, not trivia.
