  • 1. Unit 3 OCR Nationals – LEVEL 3
    Kick Start
  • 2. Getting Started
    Now there IS a Model Assignment for this beastie, and you’re welcome to follow that word-for-word. Some previous students have done that. Others have chosen a different context, and, as long as you stick to the tasks, that’s cool.
    Guidance for this is taken from the MA, available on the Exam Board website as well.
  • 3. Scenario – Model Assignment
    Is the cost of dental treatment giving us toothache?
    In August 2007 the Department of Health announced that 28.1 million people went to an NHS dentist in England in the year to March. This figure was 50,000 fewer than in the previous year. Initial studies suggest that in the UK approximately 50% of adults and 30% of children* fail to visit a dentist.
    You have been employed by your local Primary Care Trust (PCT) to undertake a study which will investigate this issue in your local area. The results of your findings will be used to make informed decisions on spending and on strategies to encourage particular groups of people to take better care of their teeth.
    *Children are defined as under 18 years of age.
  • 4. Scenario – Model Assignment
    Questions that need to be answered include:
    What is the biggest reason for people failing to visit NHS dentists? Is the reason the same for different groups, eg gender, age, social group?
    Do young people care more/less about their teeth than older people?
    How does the local population compare with the national picture? Are local people more or less concerned about their teeth than the rest of the country?
  • 5. Scenario - options
    Are children more likely to be fatter if they play more than x hours per day on a console?
    Are children better at ICT if they have a PC or Mac at home?
    Is it more cost effective to take a bus than drive a car in a city like Sheffield?
    Do students with EMA forms attend classes more regularly than those without?
  • 6. Scenario - options
    Now these are just questions to get you thinking – you would need to think about a proper scenario if you want to use any of them: chat if you do and we’ll work something out.
  • 7. AO1: define the problem
    You need to come up with a preliminary report:
    The background to the problem
    The hypothesis you will be testing
    The data you will collect
    The way in which you will collect the data
    The processing of the data that you plan
  • 8. AO1: define the problem
    So, for the dentist one:
    what has changed in the NHS recently with regards to dental treatment
    how much it costs for dental treatment on the NHS and how these costs have changed over time
    how often people of different ages are advised to visit the dentist for a check-up
    the costs/problems that may be caused if people don’t go to the dentist
    AND THEN...
  • 9. AO1: define the problem
    Having completed your background research you should now set your hypothesis – a preliminary explanation that could account for some of the facts that you have discovered. This hypothesis should be supported or disproved after you have completed your study.
    You must make a list of the data you will need to collect in order to find out whether or not the hypothesis is true.
    You must also consider how you will process the data, once you have collected it, eg:
    what calculations will you need – max, min, average, median etc
    how can your data be summarised in tables and how this can be achieved – pivot tables, formulas etc
    what graphs/charts would be useful – pie charts, bar charts, line graphs, scatter charts, trend lines etc.
  • 10. AO1: define the problem
    Consider what you will need to do to ensure you do not infringe current data protection legislation.
    You may need to carry out some research into the requirements. You need to consider, for example:
    any restrictions this places on the data you can collect and store
    any requirements you need to meet about the way you collect and store the data.
  • 11. AO1: define the problem
    Produce a project proposal, which should be in the form of a report. This should include:
    an explanation of the background to the problem
    the hypothesis you will be testing
    the criteria that will be used to test your hypothesis
    the data you will need to collect
    the methods you will use to process the data
    what you will do to comply with data protection legislation.
    To achieve the higher levels, your hypothesis needs to be complex, suggesting ways factors such as age, gender, social class etc might affect the result. The level of detail you include in your report, and the explanations you give for your decisions, will also be determining factors in the level you are awarded for this Assessment Objective.
  • 12. AO1: Grade Guide

  • 15. AO2: design & carry out a data collection activity
    Devise a study that will ensure that you collect a wide range of suitable data from a statistically significant sample. (In other words, not just Mom, and Auntie Fred, and Sam-from-down-the-road: make it REAL)
    You will need to explain:
    which data collection method(s) you are going to use (questionnaires? Interviews? Online surveys?)
    the sampling method and size (something around 30 is gonna be a minuimum – where are you going to find 30 – 50 ‘willing’ victims???)

  • 27. AO4: Create a suitable spreadsheetto analysethe data
    Organise and format your data and results to present the information as clearly as possible.
    You might also add automated facilities (macros and buttons, folks) to speed up routine tasks like printing, or moving between sheets, in order to make your spreadsheet as efficient as possible.
    The effectiveness and efficiency of the way your data is presented will be a determining factor in the grade you are awarded in this Assessment Objective.
  • 28. AO4: Create a suitable spreadsheetto analysethe data
    Create a test plan and use this to test your spreadsheet as thoroughly as possible. Make sure that any improvements that prove to be necessary are made, to make sure your final spreadsheet is as effective and efficient as possible, producing useful and accurate data to help you prove or disprove your hypothesis.
    To achieve Pass level you must carry out at least one test and make any necessary changes.
    To achieve Merit level you must devise a test plan and use it to ensure your spreadsheet works effectively.
    To achieve Distinction level your test plan must be comprehensive, covering all aspects of your solution.
