Unit 3 - Section B: Fieldwork Flashcards
Define random sampling
Where samples are chosen at random using a random number generator to avoid bias
Define systematic sampling
When you take samples at regular intervals such as every 2m
Define stratified sampling
Where you choose samples from different groups to get a good overall representation
What is qualitative data?
Data that is descriptive (non-numerical)
What is quantitative data?
Measures of values or counts expressed as numbers
What is primary data?
Data collected that is original and collected from you
What is a hypothesis/enquiry question?
A statement/question that you will try to answer during your investigation
What is secondary data?
Data collected using already available resources
What is a sampling method?
How you decide to collect your data (Systematic, stratified, random)
Define reliable
The ability of your data to be reproduced
Define accuraccy
How close results are to the true value
Define quantity
The quantity of data you decide to collect
What is the advantage of Taunton for our human geography hypothesis?
-There were many regeneration sites which means you can do many different sites within close proximity and compare them
-Also it is small and safe meaning there is less risk of injury
What was the chosen sampling method with our human geography hypothesis and why?
-Stratified
-As there were many different regeneration schemes so we could see how they differed and the benefits they possessed
Which data collection methods did you use when you did your human geography fieldwork?
-Environmental quality assessment (EQA) - Quantitative
-Epitome words - Qualitative
What is an epitome word?
The first thing that comes to your head when you think of an area - 3 words
How did you carry out an EQA?
-Choose 4 environmental factors to look for
-Decide on a scoring system
-Grade different areas
What is one limitation to the data you collected and how can you overcome it?
-Personal bias
-Work in a group
What are the risks when doing fieldwork?
-Tripping hazards
-Crossing roads/traffic
-Weather (Rain may cause for you to trip)
What environmental factors did you check for in your fieldwork?
-Air pollution
-Noise pollution
-Street furniture (benches)
-Bins
What areas did you check in your EQA?
-Castle green
-Somerset square
-Station Boulevard
-Firepool lock
What are the advantages of a radar graph?
-Data can easily be compared and it is easy to identify which data has a better EQA
Which way did you present data from the EQA?
Radar graph
Which way did you present data from the epitome words?
Word cloud
What are the disadvantages of a radar graph?
It can become overcrowded if too much data is on it therefore harder to infer
What are the advantages of a word cloud?
You can easily get an idea about an area
It plots qualitative data
What are the disadvantages of a word cloud?
Filters out the data on how many people said that certain word
What is the advantage to GIS symbols?
You can visually see it on a map meaning patterns are easy to identify
What are the disadvantages of GIS symbols?
Difficult to see data in finer detail
Can become overcrowded
What method did you use to measure the depth of water in the river Holfod?
Used a metre rule
What did you use to measure river velocity on the river Holford?
Inpropeller
What did you use to present your data on the river holford?
-Scatter graph - discharge
-Cross profiles - width and depth
Advantages of cross profiles?
It is easy to identify patterns linking width and depth
Disadvantages of cross profile?
Comparisons are difficult as they may be drawn to different scales
Advantages of scatter graphs?
Patterns and anomalies are easily identifiable
Disadvantages of scatter graphs?
Lots of different points meaning that patterns are hard to see without lines of best fit
