Welcome to the Geography Enquiry Process!
Ever wondered how geographers actually "do" geography? They don't just read books; they go outside and investigate! For your Paper 2 Section C exam, you need to understand the enquiry process. This is the six-step "recipe" geographers use to solve mysteries about the world around us.
Whether you are investigating coastal change, river processes, urban areas, or rural deprivation, the steps remain the same. Let’s break them down so you can ace your fieldwork exam!
Stage 1: Asking the Right Questions
Every great investigation starts with an enquiry question. This is a question that can actually be answered by collecting data. It shouldn't be too broad (like "Is the UK nice?") or too simple (like "Is it raining?").
What makes a good enquiry question?
It must be measurable. For example: "How does the quality of life vary between two different areas of a city?" This allows you to go out and collect specific evidence to find an answer.
Stage 2: Methods and Techniques (Collecting Data)
Once you have your question, you need to go out and get the facts! You must use at least one quantitative method and one qualitative method.
Quantitative vs. Qualitative
Quantitative Data: These are "hard numbers." They are objective and easy to put into a graph. Example: Measuring the size of pebbles on a beach or counting the number of shops in a town.
Qualitative Data: This is about "quality," opinions, and feelings. It is more subjective. Example: Asking people how they feel about their neighborhood or taking photos of a river's flood defences.
Sampling Strategies
You can’t measure every single person or every single pebble, so you use sampling. There are three main ways to choose what to measure:
1. Random Sampling: Every person or place has an equal chance of being picked (like drawing names from a hat). It’s fair but might miss important areas.
2. Systematic Sampling: You pick points at regular intervals. For example, you measure the river depth every \(5\) meters. This ensures good coverage of the whole area.
3. Stratified Sampling: You divide your "population" into groups and sample from each. For example, if a town is \(60\%\) residential and \(40\%\) industrial, you make sure \(60\%\) of your surveys are done in the residential area.
Secondary Sources
Geographers also use "second-hand" info called secondary sources. The syllabus requires you to know specific ones for each topic:
Coasts: A British Geological Survey (BGS) geology map.
Rivers: A flood risk map.
Urban and Rural: Census data (government data about people and where they live).
Stage 3: Processing and Presenting Data
Now you have a pile of data, you need to make it look clear! This helps you spot patterns. You can use hand-drawn or computer-generated methods (like Excel or GIS — Geographic Information Systems).
Common presentation methods include:
• Bar charts and pie charts for simple categories.
• Line graphs to show changes over time.
• Scatter plots to see if two things are related (e.g., does pebble size increase as you move along the beach?).
• Choropleth maps (where areas are shaded in different colors based on data values).
• Proportional symbols (circles or icons that get bigger as the data value increases).
Quick Tip: If the exam asks you to evaluate a graph, think about whether it is easy to read or if it hides important details!
Stage 4: Analysis and Explanation
This is where you explain what the data is telling you. You look for trends (patterns) and anomalies (results that don't fit the pattern).
How to analyze:
• Identify the general trend: "As we moved further from the CBD, the environmental quality score increased."
• Use math skills: Calculate the mean (average), median (middle value), mode (most common), or range (highest minus lowest).
• Link it to geography: Use theories you learned in class to explain why something happened.
Stage 5: Drawing Conclusions
In this stage, you look back at your original enquiry question and provide an answer based on your evidence. A conclusion should never be a surprise; it should be evidenced by the data you collected and the graphs you drew.
Example: "Based on my Environmental Quality Survey (EQS), I conclude that the inner-city area has a lower quality of life than the suburbs due to higher litter scores and more derelict buildings."
Stage 6: Evaluation (Critical Reflection)
This is the "honest" part of the investigation. No fieldwork is perfect! You need to think about:
• Accuracy: Were your measurements correct? Did you use the equipment properly?
• Reliability: If you did the study again on a different day, would you get the same result? (e.g., would a town center be as busy on a rainy Monday as a sunny Saturday?)
• Limitations: What stopped you from getting better data? (e.g., lack of time, small sample size).
• Improvements: How would you fix these problems next time?
Quick Review: Key Terms for the Exam
Reliability: How "repeatable" your results are. If someone else did your study, would they find the same thing?
Validity: Does the data actually answer your question?
Anomalies: Data points that are weird or unusual compared to the rest.
Risk Assessment: Planning how to stay safe (e.g., checking tide times at the beach or wearing high-vis jackets near roads).
Common Mistakes to Avoid
• Confusing Random and Systematic Sampling: Remember, Systematic has a "system" (like every \(10^{th}\) person). Random is totally by chance.
• Forgetting to mention Quantitative AND Qualitative: The exam often asks about both, so make sure you can name one of each for your fieldwork topic.
• Being too vague in evaluation: Instead of saying "it was hard," say "the sample size of \(20\) people was too small to represent the whole town of \(50,000\) people."
Remember: In your Paper 2 exam, you will be asked to apply these steps to either a physical geography context (Coasts/Rivers) or a human geography context (Urban/Rural). For more details on those specific investigations, check the next chapters in your revision guide!
