Topic 6 - Fieldwork Flashcards
What are the 6 stages of Fieldwork?
1) Question / Hypothesis
2) Data Collection + Risk Assessment
3) Data Presentation
4) Data Analysis
5) Conclusion
6) Evaluation
What is a Question/Hypothesis?
An idea which is to be tested, it can be either proved or rejected
What is Primary Data?
Data which you collect yourself
What is secondary data?
Data that somebody else has collected
What is quantitative data?
Numerical Data
What is qualitative data?
Non-numerical, opinion based data
What is a risk assessment?
An assessment identifying how to maintain safety, being prepared in order to mitigate the risk of injury
What are examples of primary data?
- Questionnaires
- Interviews
- Counts
What are examples of secondary data?
- Published articles
- Books
- Census Data
What is an example of quantitative data?
- Counts (e.g Traffic counts)
* Measurements (e.g Beach Width)
What are examples of qualitative data?
- Interviews
* Photos
What is random sampling?
Collecting the data at random
What is systematic sampling?
Samples are chosen at regular intervals
What is stratified sampling?
Collecting equal samples from different groups of a population to ensure fair representation
What are 5 data presentation methods?
- Line charts
- Bar charts
- Pie Charts
- Radar diagrams
- Scatter Charts
What are line charts used to present?
A continuous set of data
What are bar charts used to represent?
A non-continuous set of data
What are Pie charts used to present?
Proportions
What are radar diagrams used to present?
Lots of data with many different factors on a single graph
What are scatter graphs used to present?
a continuous set of data
What are the 6 stages of Data Analysis?
1) Describe the data (overall trend)
2) Identify Patterns
3) Identify any anomalies
4) Make links between data sets (Link between Primary and Secondary Data sets)
5) Explain the data (context)
6) Statistics (MEAN, MODE, RANGE)
(Basically PEAK + Explanation + Link)
(PEAKEL)
What are the advantages of Random Sampling?
- Useful for large samples
- Avoids Bias
- Can be flexible as sample may not be possible in every location
What are the disadvantages of Random Sampling?
*Might miss parts of a population
What are the advantages of Systematic Sampling?
- Straightforward
* Ensures good coverage
