How did I got straight Es in NCEA Level 3 Statistics?
Statistics is literally the only subject I’ve never got anything less than a high Merit before. As expected, I knew I was going to get an E for my Probability Concepts external after doing lots of revision and practice. In addition to the efforts in the internals with the practice with the externals, it all adds up to an Excellence Endorsement in Level 3 Statistics.
Internals
In the written assignments, detailed elaboration, linkage to research and context is what gives you an Excellence grade. Always back your arguments with relevant research sites instead of keeping it less detailed.
Also, Our teacher gave us 4 booklets for each written assignments (internals). Link to where the booklets actually came from: Click here. They guide really well and show you what parts you need to show in the assessment, etc. It's mostly worth an Achieved, but if you want higher grade, analyze the marking schedule and highlight key words of the criteria and ask your teachers if you don't understand. Also do as much practice as you can and get regular feedbacks from your teacher.
Externals
Similarly to the external(s), learn as much content as possible then do practice questions / past exam papers as many as you can, and also mark your progress, get feedbacks from your teacher, and pick up stuff along the way that you still need to know.
Time for some throwback thursday here (LOL) - looking back at how I also got an E in the Probability Concepts mock: Click here
Back to the present, the most common Excellence questions that are likely to come out in P(concepts) exam are; relative risk, conditional probability (more than 1 likely), assuming independence, determining/discussing difference/outcomes between experimental or theoretical probability, etc.
If you want me to go in deeper detail with you about each standards, etc just contact me. Hope these helps :)
