fieldwork

Question 1

What is the enquiry question for urban feildwork

Answer 1

Has pound bury been successful in making urban living more sustainable

Question 2

Explain one way a sampling technique used to collect data for urban fieldwork helped you to collect reliable data

Answer 2

We used stratified sampling when choosing sites to conduct our research as it allowed us to collect data of all 4 phases of development in poundbury giving us good spatial coverage

Question 3

Explain one way you managed a risk associated with your primary data collection (urban)

Answer 3

Child safety around unknown individuals- working in groups, reducing vulnerability to potential threats such as kidnapping posed by working with strangers

Question 4

Explain two limitations of the method you used to collect qualitative data (rivers)

Answer 4

1) biased- a field sketch depends on the persons interpretation and drawing abilities, some features may be enhanced while others can be missed out entirely
2) lack of precision - a field sketch does not capture the full scale, measurements or finer details to the location and only takes into account one view not representative of the whole town

Question 5

Advantages of stratified sampling (urban)

Answer 5

Representative of all three phases of development in poundbury
Allows for comparing different sites
Gave a good coverage of poundbury

Question 6

Disadvantages of stratified sampling (urban)

Answer 6

Biased, chosen by the sampler
Needed prior knowledge of poundbury to choose sites

Question 7

What did we use stratified sampling to do (urban)

Answer 7

To choose 4 sites to sample in poundbury

Question 8

Whet did we use random sampling to do (urban)

Answer 8

Questionaire

Question 9

advantages of random sampling (urban)

Answer 9

Theoretically no bias- no group is given preferential treatment in the selection process
Simplicity quick and convenient

Question 10

Disadvantages of random sampling (urban)

Answer 10

Risk of unrepresentative sample by chance small random samples might not reflect all age groups
Time consuming p- never sure if your questioning a local or a visitor
Practical difficulties- people selected may refuse to respond reducing representativeness
May be biased as certain people may seem more approachable than others

Question 11

What primary data did we collect (urban)

Answer 11

Environmental quality assessment using a sliding scale from -2 to 2
Clone town survey
Questionnaire
Annotated photo

Question 12

What secondary data did we collect (urban)

Answer 12

Index of multiple deprivation data - compared poundbury to Dorchester

Crime data - compared poundbury to Dorchester

Question 13

What qualitative data did we collect (urban)

Answer 13

Annotated photo and questionnaire

Question 14

What quantitative data did we collect (urban)

Answer 14

Clone town survey, crime data, IMD, environmental quality survey

Question 15

Explain two limitations of the method you used to collect quantitative data

Answer 15

Not visually appealing - compared to charts or graphs tally charts are less engaging and harder to interpret for presentations
Lacks detail - shows frequencies but doesn’t provide deeper insights such as trends, percentages or proportions

Question 16

What did we use stratified sampling for (rivers)

Answer 16

To choose sites to collect data from

Question 17

Advantages of stratified sampling (rivers)

Answer 17

Investigate upper middle and lower course of the river
Could choose safe and accessible sites

Question 18

Disadvantages of stratified sampling (rivers)

Answer 18

Wasn’t a true representation of the whole river
Small sample size - had to use secondary data for the rest of the sites

Question 19

What did we use systematic sampling for (rivers)

Answer 19

River depth and velocity

Question 20

Advantages of systematic sampling

Answer 20

Easy to set up £ measure at regular intervals along a transect or section of the river
Even coverage- ensures the whole river section is represented rather than clustering measurements in one area

Question 21

Disadvantages of systematic sampling

Answer 21

Risk of missing key features- unusual feature like a sudden deep pool or obstruction fall between sampling points they may be overlooked
Practical challenges- maintaining equal spacing can be difficult in fats flowing water or wide rivers

Question 22

What primary data did we collect (rivers)

Answer 22

Width and depth ( calculate cross sectional area)
Velocity (with cross sectional area could be used to calculate discharge)
Rock size (a axis)
Rock angularity
Field sketch
Gradient

Question 23

What secondary data did we collect (rivers)

Answer 23

Previous data from other sites
1:25000 ordnance survey map

Question 24

What peice of equipment is used to measure gradient

Answer 24

Clinometer

Question 25

Explain one factor that affected the decision on the sites you chose to collect your data

Answer 25

We chose sites that showed different types of Landu use such as commercial and recreational areas to get a balanced view of sustainability in poundbury

Question 26

Explain one way secondary was used to support your enquiry (urban)

Answer 26

We used the index of multiple deprivation data to compare poundbury to Dorchester. This helped us understand whether sustainability efforts were improving quality of life

Question 27

Explain one advantage and one disadvantage of a data presentation technique used in your enquiry (urban)

Answer 27

Radar graph gave us a visual representation and allowed us to compare multiple sustainability indicators at once making it easy to visually identify which area was most sustainable However it only showed a snapshot of the sustainability indicators poundbury not changes over time

Question 28

Suggest one reason the conclusions from your enquiry were reliable

Answer 28

Our conclusions were reliable as we recorded data from different areas in poundbury this allowed us to compare different types of land use like green spaces and commercial and reduced bias by giving s more complete picture of sustainability across the whole area

Question 29

Explain one primary data method used in data collection (river)

Answer 29

We used systematic sampling to produce data on the depth of the river at different sites. To do this we used a meter ruler and measured the depth of the water at regular intervals from one bank to the other and then found the mean. This is easy to carry out and uses the average depth so it is representative of the whole channel

Question 30

What did we use to measure the velocity of the water

Answer 30

A flow meter

Question 31

Evaluate the use of scatter graphs (rivers)

Answer 31

The scatter graphs were effective because by drawing a line of best fit they showed how velocity changed with distance downstream and whether there was a clear positive trend as predicted by the Bradshaw method aswell as allowing for anomalous to be spotted However the scatter graphs could be misleading as only a small number of sites were measured meaning individual anomalies had a big effect on overall trend

Question 32

Evaluate the use of cross sectional diagrams (rivers)

Answer 32

Clearly illustrated changes in channel width and depth helping me to see how the rivers shape developed downstream which was a key component of the model. However the accuracy was reduced by the difficulty of measuring depth consistently across the channel

Question 33

Evaluate the use of located circled on gis for pebble size

Answer 33

The located pie charts in GIS were especially useful mad they showed both the size and spatial distribution of the bedload making it easy to compare sites and test whether pebble size decreased downstream which they did
