What was a strength of the hypothesis?
It could clearly be proved true or false
What limitation affected the hypothesis?
It did not consider upper-floor land uses and services
How could the enquiry have been improved?
By investigating upper levels of buildings as well
Why was Les Halles a good investigation site?
It had experienced major redevelopment over the last 10 years
Why was Google Street View useful?
It showed detailed images before redevelopment
Why was the site good for questionnaires?
Large numbers of shoppers were available to question
Why was the site considered safe?
It was an open public space with traffic calming measures
What weather problem affected the investigation?
Cold windy rain made data collection difficult
How did weather affect questionnaires?
Fewer people were present to answer questions
Why was surveying buildings difficult?
Many buildings had multiple levels with different services
What issue made comparisons between 2016 and 2026 difficult?
Some shops merged or buildings changed completely
What was a strength of the EQS sampling strategy?
It created a logical systematic grid around Les Halles
Why was pragmatic sampling useful?
It adapted sites so they were practical and safe to survey
What was a weakness of pragmatic sampling?
It could be biased by the investigators’ opinions
How were questionnaire respondents selected?
By rolling a dice and counting people randomly
Why was random sampling useful?
It reduced bias
What limitation affected questionnaire sampling?
Pupils may have avoided intimidating people
Why were interviews carried out pragmatically?
To target a range of shop types and viewpoints
Why were photographs useful?
They added detailed qualitative evidence to conclusions
What issue existed with Google Street View?
Some angles and locations could not be viewed clearly
How could sampling reliability be improved?
By increasing the number of survey sites
Why were repeat readings important?
They improved reliability and reduced anomalies
Why was one person responsible for readings?
To improve consistency
What weakness affected land-use categories?
High
How could land-use categories be improved?
Create fixed lists for each category
How did poor weather affect EQS results?
It may have encouraged more negative scores
How did weather affect photographs?
Fewer photographs were taken during rain
Why could news reports contain bias?
Many came from government-linked agencies
How could secondary data reliability improve?
Use more sources hidden behind paywalls or other photo sites
Why were radial kite graphs useful?
They clearly showed differences visually
What did smaller circles on radial kite graphs represent?
Lower environmental quality scores
Why were tables still needed with radial kite graphs?
To provide exact numerical values
What limitation affected the land-use map?
It only showed ground-floor land uses
How could the land-use map improve?
Use two colours to compare before and after redevelopment
Why were bar graphs useful for questionnaires?
They clearly showed differences and trends
Why were annotated photographs useful?
They explained why photos were important
What problem affected Google Street View photographs?
Traffic blocked some important views
How were EQS results analysed?
By comparing radial kite graphs and averages
What did the EQS averages show?
Areas near Les Halles had higher environmental quality
What change occurred in high-order shops?
They increased from 1 to 3
What happened to medium-order shops?
They decreased from 15 to 9
What happened to low-order shops?
They decreased from 11 to 6
What did questionnaire averages suggest?
People generally had positive opinions about redevelopment
Which questionnaire topic scored lowest?
Quietness in the area
What was the average score for positive redevelopment effects?
4.3 showing strong agreement
Why was the land-use hypothesis inconclusive?
Different numbers of buildings made comparisons unreliable
What major weakness affected land-use reliability?
Upper-floor services were not measured
How could land-use reliability improve?
Create maps including multiple building levels
What did Hypothesis 1 conclude?
Environmental quality was higher around Les Halles
What evidence supported Hypothesis 1?
Les Halles averaged 0.6 while surrounding areas averaged -0.4
What limitation affected Hypothesis 1?
Only 9 sites were surveyed
How could Hypothesis 1 be improved?
Use more sites with systematic sampling
What did Hypothesis 2 conclude?
Environmental quality improved after redevelopment
What evidence supported Hypothesis 2?
Post-development scores were higher than pre-development scores
What limitation affected Hypothesis 2?
Google Street View limited some views
What improvement was suggested for Hypothesis 2?
Use additional online images
What did Hypothesis 3 conclude?
People had positive opinions about redevelopment
What limitation affected Hypothesis 3?
Too few questionnaire respondents due to poor weather
How could Hypothesis 3 be improved?
Repeat surveys on a better weather day
What did Hypothesis 4 conclude?
Land-use change results were inconclusive
Why were land-use results unreliable?
Different building numbers and no upper-floor data
What improvement was suggested for Hypothesis 4?
Measure upper-floor land uses and redesign maps
What is an anomaly in fieldwork?
A result that does not fit the overall pattern
Why is repeating surveys important?
It improves reliability and reduces anomalies
What is subjective data?
Data based on opinions or judgement
What is objective data?
Data based on measurable facts
What is the purpose of evaluation in geography fieldwork?
To assess strengths
