Does hard engineering prevent longshore drift in Swanage?
Tourism has an environmental effect in Swanage.
Why was the area chosen? (Physical)
The area was chosen because it was easily accessible by coach (a few hours away)
Swanage has hard engineering so we can test the hypothesis.
Why was the our physical hypothesis valid?
Because we can easily test the theory that hard engineering prevents longshore drift
Risks of collecting data
Rocks could fall from cliffs
We could be washed out to sea if we get too close to the shore.
Risk of sun stroke or sun burn
Data collection method
Groyne drop height survey. We used a tape measure to test the beach build up on the north and south side of 5 groynes along the beach. We used systematic sampling of each of the 5 groynes.
Sampling method for collecting data?
Systematic sampling was conducted to ensure that the data collected gave us a clear view of different areas of the beach.
Problems with method
We could have used a digital measure to make the data collected more accurate.
We could have sampled more groynes to make our data more reliable
A description of how close a measurement is to the true value of the quantity measured.
the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting.
the extent to which a test measures or predicts what it is supposed to
Why was the Human title valid?
It was easy to collect data about the possible environmental impacts of tourism as Swanage is a tourist honeypot.
What was the aim of the study?
To find out whether tourism had an environmental impact in Swanage
Collection method for environmental impact
Environmental quality survey was completed in 3 tourist and 3 non-tourist areas in Swanage. We assessed 16 different measure of enviornmental impact in each of these areas.
We completed photo analysis of a photograph taken by somebody else to see what evidence of environmental impact there was.
Collection method for EQS
We did a transect of Swanage and then a systematic sample along each transect in the tourist and non-tourist areas.
Problems with EQS
We only completed the survey on one day at one time of year.
The EQS included some element of opinion - the scores we gave were subjective.
Problems with photo analysis
The photographs did not necessarily give the whole picture of the scene - they can be focussed on certain elements to create bias.
Data presentation techniques
We presented data from the EQS in the form of radar graphs. This allowed us to see many variants on one graph, also allowing us to see trends more easily.
How could our human study be improved?
Data could have been collected on multiple occasions to see if anything changed.
We could have used a key to give us an idea on how to score the EQS factors which would have made our data more accurate and less subjective.
How could mitigate the risks on our human fieldwork?
Carry a map and make note of a known landmark in case we get lost.
Take sun tan lotion and plenty of water.
Always use a pedestrian crossing when crossing roads to prevent accidents.
What is quantitative data?
Data that is numerical or that is referring to measurements or amounts.
What is qualitative data?
Data which is non-numerical, often based on opinions or observations
Systematic sampling is
Collecting data at specific intervals
Stratified sampling is
a variation of random sampling; data collected from two specific ends of the town
Random sampling is
Data collected without any pattern or plan without any order
Primary data is
Data collected by ourselves
Secondary data is
Data collected by someone else and then used by us
How do you work out the mean?
Add the total of all the values and then divide by the number of values
How do you work out the median?
Write out all of the numbers which have been collected in order, then find the middle number
How do you work out the mode?
The most commonly appearing value within the data set
