What this dot point is asking
WACE wants you to use the inquiry process as a tool, not recite it. A strong answer applies the relevant stage to the scenario, evaluates the reliability and validity of data, and links conclusions to a planned action. Marks reward correct application and judgement about evidence.
The stages of the health inquiry process
The process begins with planning: identifying a health issue, framing a focused inquiry question, and deciding what data are needed and how to collect them ethically. Data collection follows, drawing on primary sources (data the investigator gathers, such as surveys, interviews or observations) and secondary sources (existing data, such as government statistics, reports and research). Analysis and interpretation involve organising the data, identifying patterns and trends, and making sense of what they show. Drawing conclusions means answering the inquiry question from the evidence and acknowledging limitations. Finally, the findings inform action: planning health promotion strategies and advocacy that respond to what the inquiry revealed.
Primary and secondary data
Choosing data sources is a key skill. Primary data are tailored to the exact question and current, but can be time-consuming, costly and limited in scale. Secondary data are often large, authoritative and quick to access, but may not fit the specific question or population and can be out of date. Good inquiries combine both, using secondary data to establish the broad picture and primary data to capture local or specific detail. Evaluating the source, sample, method and purpose of each dataset determines how much weight to give it.
Analysing data and drawing conclusions
Analysis turns raw data into meaning. This involves summarising results, comparing groups, identifying trends over time, and interpreting graphs and tables. Conclusions must follow from the evidence and stay within its limits, noting sample size, bias, currency and whether the findings can be generalised. Recognising the limitations of a study is a marker of strong analysis, because it shows you understand how confident the conclusion can be.
From evidence to action
The purpose of inquiry in this course is action. Once conclusions are drawn, they should shape health promotion and advocacy: choosing Ottawa Charter action areas that fit the identified problem, targeting the determinants the data revealed, and prioritising the groups most affected. Evidence-based action is more likely to be effective and more defensible than action based on assumption, which is why the inquiry process and health promotion are taught together.
How this maps to the exam
Expect a stimulus presenting data, a study design or a proposed investigation. You may be asked to identify a stage of the process, evaluate the reliability or validity of a method, interpret data, or use findings to plan action. Apply the specific stage to the stimulus and justify your judgements about the evidence.
