Edexcel GCSE Geography A (1GA0) — Geographical Investigations: Fieldwork and UK Challenges
How do geographers measure something as complicated as a bustling city? Edexcel Specification A requires you to use both qualitative data and quantitative data to investigate an urban environment.
For this specific exam board, measuring the land use function is your required quantitative method. Recording the environmental quality is your required qualitative method.
Even though an Environmental Quality Survey (EQS) produces a numerical score, examiners classify it as qualitative because it relies on human perception and subjective judgement.
Understanding what buildings are used for helps planners see if a high street is thriving or failing. You must objectively categorise buildings using the standard RICEPOTS classification mnemonic.
RICEPOTS stands for Residential, Industrial, Commercial, Entertainment, Public, Open Space, Transport, and Services. To collect this data objectively, you walk along a route and keep a tally of each building's function, or measure the shop frontage length using a tape measure or pacing.
When surveying dense areas like a Central Business District (CBD), students apply the 'ground floor rule'. You only record the ground floor use to ensure consistency, though multi-story usage can be noted to show vertical diversity.
How do you calculate the percentage of commercial land use at a site?
Step 1: Identify the values from your survey.
Step 2: Substitute into the equation.
Step 3: Calculate the final answer.
Two people might look at the exact same graffiti—one sees vibrant street art, while the other sees vandalism. This is subjectivity, which makes recording environmental quality challenging.
Students use an EQS to assess the physical and aesthetic "feel" of an area based on indicators like litter, noise, and building condition. These are scored using a bipolar scale, which provides a range between two opposite adjectives (e.g., a scale from -3 to +3, where 0 is neutral).
To reduce subjectivity and make your results more reliable, you can conduct a pilot study to agree on what a "+2" looks like. Alternatively, work in pairs to reach a consensus score or calculate a mean score from multiple observers.
How do you calculate the total environmental score for a site? (Scale: -2 to +2)
Step 1: Record the individual category scores.
Step 2: Sum the scores together.
Step 3: State the final score.
To support your EQS, you should use an annotated field sketch or an annotated photograph. A good annotation combines a direct observation with a geographical explanation. For example, your EQS might capture negative scores for boarded-up shops and excess litter, which you can annotate as indicating urban decay. Conversely, high scores might be supported by annotating 'modern glass-fronted developments indicating recent regeneration'.
If you walk from the very centre of a city out to the suburbs, you will notice the scenery slowly changes. To capture this change, geographers collect data along an urban transect—a straight line radiating outwards from the CBD.
To ensure your data is objective and represents the whole area, you must use systematic sampling. This involves stopping to collect data (EQS and land use tallies) at fixed, regular intervals, such as every 200 metres or every 5th building.
If you wanted to compare two very different zones, such as an industrial estate and a residential suburb, you would use stratified sampling. This means deliberately choosing specific streets that represent those distinct environments.
The way you choose to draw a graph can completely change the story your data tells. For qualitative EQS data, a radar graph (spider diagram) or bipolar bar chart is the most effective way to visually compare multiple sites.
Quantitative land use data is best presented using a divided bar chart, proportional pie chart, or a colour-coded map. You can also use GIS software like ArcGIS to layer your primary land use data over secondary data, such as Lower Layer Super Output Areas (LSOAs) or Goad maps.
A limitation of divided bar charts is that they show proportions rather than raw totals, making it difficult to compare sites if the total number of buildings surveyed varies significantly. You must analyse these graphs to prove or disprove a hypothesis, such as "Environmental quality improves with distance from the CBD."
Students often state that an EQS is quantitative because it produces numbers. For Edexcel Spec A, you must remember that an EQS is qualitative because the scores are based on subjective human perception.
If an exam question asks you to 'Apply' your knowledge to explain why you chose a transect, you should state that it allows you to investigate the transition in land use and environmental quality moving outwards from the CBD.
When evaluating your methodology, examiners award high marks for explaining exactly how you reduced subjectivity in your EQS (e.g., by carrying out a pilot study to standardise your bipolar scale).
If asked about the limitations of data presentation, mention that divided bar charts only show proportions (percentages), meaning you lose the raw total count of buildings surveyed at each site.
Qualitative data
Descriptive information based on human perception, feelings, or observations, such as field sketches or environmental quality surveys.
Quantitative data
Numerical information that can be counted or measured objectively, such as land use tallies or building frontage measurements.
Land use function
The specific purpose or activity for which a building or area of land is used.
Environmental Quality Survey (EQS)
A qualitative fieldwork method used to subjectively assess the physical and aesthetic characteristics of an urban area.
RICEPOTS
A standard land-use classification mnemonic used to objectively categorise urban buildings (Residential, Industrial, Commercial, Entertainment, Public, Open Space, Transport, Services).
Central Business District (CBD)
The commercial and economic core of a city, where retail and office land uses are most heavily concentrated.
Tally
A simple method of recording quantitative data by making marks for each item counted, often used for land use surveys.
Subjectivity
The influence of personal opinions, feelings, or tastes on data collection, making it less purely objective.
Bipolar scale
A rating scale used in an EQS where observers choose a numerical score between two opposite descriptive extremes (e.g., -3 to +3).
Urban decay
The deterioration of an urban area due to neglect, economic decline, or population loss, often characterised by boarded-up buildings and poor environmental quality.
Regeneration
The process of improving a declining urban area by investing in new developments and upgrading the physical environment.
Annotated field sketch
A hand-drawn geographical drawing that includes detailed explanatory text linking observations to geographical theories.
Annotated photograph
A photograph taken in the field that has been labelled with explanatory notes detailing geographical processes or features.
Urban transect
A line or path through a city—usually starting at the CBD and moving outwards—along which data is sampled to show environmental changes.
Systematic sampling
A data collection technique where survey sites are chosen at regular, predefined intervals (e.g., every 200 metres) to remove human bias.
Stratified sampling
A sampling method where specific sites are deliberately chosen to proportionally represent different subgroups or zones within an area.
Radar graph
A circular chart (often called a spider diagram) used to plot multivariate data, highly effective for visually comparing EQS scores between different sites.
Divided bar chart
A graph where a single bar is split into segments to show the percentage or proportion of different categories, often used for land use data.
