Study with Edmund Liew

Assumptions -  If you open the following link and turn to Page 4 in this pdf file you will see that this candidate made a few possible assumptions of her experiments. You can also use that kind of assumptions in your test too; just make sure the context is different (lol). You can also look back at her work to see what she meant by all these assumptions. http://www.nzqa.govt.nz/.../Mathematics/91268/91268-EXP.pdf· 

And for reflections; provide reasons how you can improve this experiment. What would you do if you were to repeat this experiment?? And I would say provide at least 3 relevant assumptions and 3 relevant reflections just to be sufficient for an E. 

Hello @traya-ren, thank you for your message.

Unfortunately, I did not do Calculus. I’ve only done NCEA Level 1 Right Angled Triangles which might not be relevant to you. However, there are NZQA resources that might help, such as:

Standard Outline clearly showing topics you need to learn and do for A/M/E - http://www.nzqa.govt.nz/nqfdocs/ncea-resource/achievements/2017/as91575.pdf

and

NZQA Exemplars showing A/M/E work done by students - http://www.nzqa.govt.nz/assets/qualifications-and-standards/qualifications/ncea/NCEA-subject-resources/Mathematics/91575/91575-EXP.pdf

and other resources.

You can also ask on the NCEA Resources Page on Facebook and I’m sure there will be someone that can help.

Hope these encourages,

For Stats 1.10 Multivariate Data / 2.9 Inference, you can literally follow this checklist that can get you a Merit or Excellence.

1) PROBLEM - I wonder if ... (comparison between two groups) and show the (population of your data). State your prediction and describe why. Support with research and link it to context where necessary. 

2) PLAN - What are you going to do? - Where are you going to collect data from? - What happens if you did the sampling again? - What are your variables? - Modify or clean your data, if necessary.

3) DATA Place your graph with appropriate conventions (appropriate title and keys) that shows comparison between two groups.

4) ANALYSIS - Discuss statistical features; mean/median/mode, range/interquartile range, overlaps, and unusual/interesting features. Support with specific figures and units. Make sure they are also linked to context. Provide possible reason to why are the figures this way? Support your discussion with research and link back to context where appropriate too.

(Level 2 only). - Start talking about informal confidence interval. This is the vital part for Merit/Excellence. What are the informal confidence intervals for two groups and make sure you show your calculation as well as the formula of how you calculated it. I guess you might be using this formula if I'm not wrong: 

median ± 1.5 * (Interquartile range) / square root(number of samples). 

And link your calculations to context. Determine whether there's overlap between the intervals or not. 

This 91260 (2.5) standard is worth 2 credits and contributes to your Level 1 Numeracy requirement.

In this standard, the numerical units you will be likely to use are not limited to; distance (length) but also cost and scenery rating.

You are very likely to be given a real life issue / mathematical context in your test rather than a simple  question. Such as; you might be given a route of major roads in Auckland / Hawkes Bay cycleways, or anything like that.

For an Achieved, you need to correctly calculate the minimum and maximum values and also determine correctly whether the network for this case study is traversable or not. Also you need to show drawings and some brief descriptions. Make sure your communication is also clear.

For a Merit, you need to describe why/why not the network is traversable and also describe how you found shortest/longest routes (what methods?), etc. And also you need to be able to decide by yourself which route would you like to keep/remove to cater for groups of people's needs and explain why. And sum up the total length/cost/etc. It's up to you to decide but you need to support your decision with specific evidence relating to costs/distance etc and which groups will/won't it serve, etc.. (hope that makes sense)

And for an Excellence, you need to: - Devise a new strategy - merge all features into one tree. For example, let's assume you've got 3 separate networks (each showing length, time taken and scenic rating). you gotta condense them into one. There would be lots of decision making so I'd strongly recommend you plan first. Decide wisely though which route do you wanna keep and which one do you not want to have. You also need to justify why and how would this decision affect groups of people. You also gotta say whether your new strategy would be traversable or not (and why?) And you could also talk about improvements (what can be better?).

I guess that's what you gotta do for this internal. Contact me anytime if you have any queries. Your feedbacks and suggestions will also be greatly appreciated. 

Do lots of reading to enhance your thinking, analyzing and writing skills. Because this year, you are 'likely' to sit either 2.8 Info Literacy standard, 2.9 Personal Responses and/or 2.4 Writing Portfolio. 

In the 2.8 you will be required to do research across different sites/sources for information and evaluating them, etc. 

In your 2.9 Personal Responses, you will be reading and personally responding to 6 texts (2.9 takes all year to do it). Pick books/texts that you're knowledgeable at, passionate at, and/or that can resonate with you, so it makes understanding easier. Or if you want/can, you could also pick more challenging texts so you could see how you go along with it. 

In the 2.4, you must have NO spelling, grammatical or punctuation errors if you really want a pass. This is worth 6 credits and contributes to your UE Writing credits - because it does contribute to getting your UE by just passing it, it is most likely schools would do it. One way I would suggest preparing for this is, practice your writing skills during the year, try to write formally instead of non-formally so once you're in a habit of doing them, you're ready for the assessment. This one involves thorough proofreading for errors / make sure what you talk about in it makes sense and if it's not understandable you must explain it/make it clear. Structuring is also vital. This is one of the hardest standards unless if you're really good at these. 

And for externals, practice writing essays too/unpacking essay questions/planning your essay, etc. Read/Understand questions carefully before you answer them - just to avoid careless mistakes.  I got an M in my 2.2 essay external despite English is my weakest subject so the externals are my strength. But also practice with essays during the year if you can (so you are well prepared for end of year exams)

**LONG POST ALERT** Geography was my favorite subject in Year 11 and always cared for it and basically neglected other subjects lol. I got a Merit Endorsement in Level 1 Geography (so close to Excellence but, oh well). I’m so happy to share with you what I’ve learnt in this subject after a successful year also a successful completion of 3 levels of NCEA. Geography is a study of human interactions with our natural and cultural environment. 

1) If you really want an E

2) If you believe that they marked wrongly or unfairly and you want them to remark it,

Then yeah you should.

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.

After seeing my Geography result, I’m so surprised and happy that I got an E for my Natural Processes external, therefore leading to an Excellence Endorsed in Level 3 Geography. I will share with you how I got all Es, in terms of important things you need to do.

Internals

One way I got Es in internals, is work on the assignment at least every day or many times a day, this includes doing research for relevant information needed. Gather as much relevant data as possible and show not just one but like three relevant examples for each aspect and also analyse them (like explaining how/why). Incorporate relevant key concepts too (must for E) and geographic vocabulary (don't use general words like we do in everyday convos) and explain how they are shown in your case study/aspect/etc. Don't forget specific figures - e.g dates/times/costs/etc. Oh, almost forgot, incorporation of relevant annotated diagrams/maps/graphs* may be used too - they increase your chance of getting E. *Annotated diagrams/maps/graphs must have appropriately demonstrated conventions (e.g titles, naming, FIGURES, axis, etc) - especially with 3.5 Research standard. Externals

Wait... u weren’t allowed to what?? lolBut hey awesome work for what you’ve done in L2 English!! Thanks for letting me know how you went (makes me feel better to know that it all helps :) ). I hope you end up with high marks!! And awww.... how nice of you to leave a sincere note to the marker - I’m praying it comes back an E!!!
