What this dot point is asking
CCEA Unit A2 2 is the internally assessed Research Project, not a written examination. This single overview sets out what the project involves: choosing a focused research question, planning a sound and ethical methodology, gathering and analysing primary and secondary data, drawing evidence-based conclusions, and presenting the work as a structured report. The detail of any particular investigation depends on the question chosen, so this page covers the process and the skills the assessment rewards rather than a fixed body of content.
How the Research Project works
The project moves through clear stages. You choose a research question or hypothesis that is focused and manageable within the time and resources available. You plan the methodology, deciding what primary data to collect (for example a questionnaire, survey, interview, sensory-analysis test or practical investigation) and what secondary data to draw on (textbooks, journals, reputable websites, government and health-body reports), while considering the sample, validity, reliability and any ethical issues such as consent and confidentiality.
Analysing, concluding and presenting
You then carry out the research, recording data accurately and systematically, and analyse it using suitable tables, graphs, charts and simple statistics, looking for patterns and relating the findings to the secondary research. You draw evidence-based conclusions that answer the original question, acknowledge limitations, and suggest improvements or further research. Finally you present the work as a structured report with a logical sequence, correct referencing of sources, and accurate subject terminology.
Examples in context
Example 1. A sensory-analysis investigation. A student investigating whether reducing the sugar in a recipe affects how much people like it runs a sensory-analysis taste panel (primary data) comparing standard and reduced-sugar versions, and reads about sugar-reduction and sensory testing (secondary data). Analysing the panel ratings against the wider evidence lets the student draw a balanced conclusion, showing the project method applied to food science.
Example 2. A questionnaire on food choice. A student exploring the factors that influence their peers' food choices designs a questionnaire (primary data) and compares the results with published work on food choice (secondary data). This links the project directly to the factors-affecting-food-choice content of Unit A2 1, illustrating how the project draws synoptically on the taught units.
Try this
Q1. Explain the difference between primary and secondary data. [2 marks]
- Cue. Primary data is collected by the researcher for the investigation; secondary data is already published by others.
Q2. State two things a researcher should consider when planning a method. [2 marks]
- Cue. Any two of: the sample, validity, reliability, and ethical issues such as consent and confidentiality.
Q3. Explain why a research project should acknowledge its limitations. [2 marks]
- Cue. It shows honest, balanced reasoning, makes the conclusions more credible, and allows sensible suggestions for improvement or further research.

Because Unit A2 2 is internally assessed coursework rather than a written exam, this is a guidance-style answer about the process the assessment rewards.
First, choose a focused, manageable research question or hypothesis on a nutrition or food-science topic, narrow enough to investigate in the time and resources available. Second, plan the methodology: decide what primary data to collect (for example a questionnaire, a survey, a sensory-analysis test or a practical investigation) and what secondary data to use (textbooks, journals, reputable websites, government reports), and consider the sample, validity, reliability and any ethical issues such as consent and confidentiality.
Third, carry out the research, gathering the data systematically and recording it accurately. Fourth, analyse the data using suitable tables, graphs, charts and simple statistics, looking for patterns and relating the findings to the secondary research. Fifth, draw evidence-based conclusions that answer the original question, acknowledging limitations and suggesting improvements or further research. Finally, present the work as a clear, structured report with a logical sequence, correct referencing of sources, and appropriate use of subject terminology.
A strong project shows a focused question, a sound and ethical method, accurate data handling and analysis, and balanced, evidence-based conclusions that link primary findings to wider research.
CCEA A2 (coursework guidance)6 marksDiscuss the difference between primary and secondary data, and explain why a research project should use both.Show worked answer →
This guidance-style answer reflects the research skills the internally assessed project rewards.
Primary data is information the researcher collects themselves for the specific investigation, for example through a questionnaire, survey, interview, sensory-analysis panel or practical experiment. Secondary data is information already gathered and published by others, such as textbooks, journal articles, government and health-body reports and reputable websites.
A good project uses both. Secondary data provides background, defines key terms, shows what is already known and helps form the research question and hypothesis. Primary data then tests the question directly in the researcher's own context and produces original results. Comparing the two strengthens the conclusions: the primary findings can be interpreted against the wider published evidence, and agreements or differences can be discussed. Using both also improves validity and shows balanced, well-supported reasoning.
Markers (in the coursework criteria) reward a clear definition of each, examples, and the explanation that secondary data informs the question while primary data tests it, with the two compared in the analysis.
