Question 1

What is NCEA AS 91038 about?

Accepted Answer

This standard asks you to investigate a real-world situation that involves chance or randomness (like rolling dice, sampling students, or testing a prediction about random events). You'll need to run an experiment, collect data, display your results, and compare what actually happened to what the maths predicted would happen.

Question 2

What do students need to do for AS 91038?

Accepted Answer

1. Ask a clear question about a situation involving chance and decide what you want to explore 2. Plan and run an experiment or investigation, deciding what outcomes are possible and how many trials you'll do 3. Collect your data and organize it using displays like frequency tables, graphs, or probability distributions 4. Compare your experimental results (what actually happened) to the theoretical probability (what should happen mathematically) 5. Communicate your findings clearly by explaining patterns in your data and what they tell you about the situation

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91038?

Accepted Answer

Achieved: You carry out an experiment involving chance, collect data, display it, and describe what you found without necessarily linking it back to the original question. Merit: You connect your findings to the question you asked, support your conclusions with evidence (like statistics or trends from your displays), and justify why your results make sense. Excellence: You show deep understanding by bringing in outside knowledge about probability and the context, considering how other factors might affect results, and integrating all of this into your conclusions.

Question 4

What mistakes do students typically make in AS 91038?

Accepted Answer

1. Not asking a clear question at the start or not linking your conclusion back to that question 2. Running too small a sample size so your experimental results are too random or unreliable 3. Presenting data displays without explaining what patterns you see or what they mean
