Housing decay survey ~ CE
79% good/excellent
21% sufficient
Housing decay survey ~ EV
100% good/excellent
what does housing decay survey demonstrate
differences between 2 adjacent areas of EL through the differences in their quality of housing
lack of investment in CE compared to EV
Env quality survey CE
mean ~ 24.15
median ~ 24
range ~ 31
IQR ~ 13.5
Env quality survey EV
mean ~ 6.08
median ~ 5
range ~ 19
IQR ~ 3.5
What does env quality survey show
lower IQR + range for EV show an overall better environmental quality as there’s less variation in the data
shows success of regeneration project
dispersion graph to plot env quality is good why
shows the spread of data
shows averages
removed anomalies
easy to construct
how does this investigation link to a geo theory u have studied
links to the regeneration plan we have studied
suitable for this enquiry bc we are able to see the effects of the plan + its success
can see opportunities + challenges
why was stratford a good location to visit + conduct fieldwork
easy to access from school ~ no restrictions + easy walking distances between the areas
good location to show the differences in inequalities as EV has been regenerated whereas CE hasn’t
can collect wide range of data
housing
env
able to collect data in one day
limits how much can be collected however + data collected may not be as reliable depending on the day
cross section protected
32.5 m² ~ area
2.5 m ~ height
cross section unprotected
25m² ~ area
2m ~ height
what shown
line graphs show that protected has more sediment showing effectiveness of management strategies
protected ~ groynes
but more sediment closer to the groynes which could lead to inaccurate results + therefore an invalid comparison
protected ~ sea wall
prevents beach extending too far + maintains steeper gradient
can’t compare lengths of beach as limited to 25m
but due to differential erosion we can assume unprotected is longer
unprotected has smaller CSA as cliff erodes back creating a wider beach
class cross sections protected
median ~ 30
mean ~ 29.8
IQR ~ 12.75
class cross sections unprotected
median ~ 24
mean ~ 26. 4
IQR ~ 10.5
what shown
protected beach shows wider spread of data showing that the data for the unprotected beach is more accurate compared to the protected beach
larger IQR for protected shows that the groynes are working bc they prevents longshore drift, creating bigger variations in the CSA
mean + median useful in removing anomalies
beach sediment protected
96% sand
4% clay
beach sediment unprotected
72% sand, 16% shingle, 12% shingle
pie chart show what
shows there’s more variation in the sediment of the unprotected beach
beach sediment being mostly sand for the protected beach show that the seawalls protect the beach by preventing new sediment falling on the beach
beach profiles methodology
systematic sampling
relatively quick
removes bias ~ every 5m
not very accurate
lots of room for human error
could’ve used ranging poles instead
only every 5m
smaller intervals would be more precise
env impact assessment
stratified sampling
quick
no equipment needed
numerical data ~ can be compared easily (quantitative)
opinionated
perception and personal preference (MS)
0-5 scale could be easily misinterpreted
beach sediment
random sampling
quick, numerical data
room for human error
hard to distinguish what area of a quadrat something may be covering
mean/median/mode/range
mean ~ considers all values
range ~ used to identify increase/change
mode ~ many measurements are the same
