Data, probability and statistics I

Use the objectives and challenge below for reflection or a conversation with someone who can help. This is guided self-assessment: it sends no answers, awards no XP and does not automatically verify independence.

In Foundations, change an example, predict results, check a normal case and an error case, and explain your choices. If you need help, identify what to practice again.

Your transfer challenge

Create a second dataset with at least eight fictional deliveries. Ask another question, include a boundary case and record when your recommendation would change. After a few days, compare your initial and revised explanations.

Keep evidence: prediction, attempt, result, an original change and what you still cannot explain. Seek feedback when possible; if studying alone, return later without copying and compare attempts.

Try again another time

After a break, explain the idea without opening the solution and try a different example. Compare with your first attempt: what can you do independently, and where do you need a hint? You may write, speak or draw; choose a way to check the same idea. Record help received, including AI, and revisit the part you need. There is no universal deadline or extra XP for this record.
