  • undertake pilot study - smaller/quicker version of actual
  • check you know how to use equipment/that its suitable
  • finetune methodology
  • test data collection actually works
  • assess time allocation
  • assess value helping to improve validity/reliabilty/accuracy of data

EXPLAIN WHY A QUESTIONNARE CAN BE UNRELIABLE FOR PRIMARY DATA COLLECTION

  • low response rate
  • people may be untruthful or lie meaning not valid
  • if open difficult to analyse and record responses
  • if closed revoke irritabilty and people gve first/shortest repsonse
  • poorly designed with too many closed/open
  • time consuming
  • pragmatic
  • puplic resistance  meaning sample size reduced and irritabilty/skewering of results

OUTLINE 2 ADVANTAGES OF CARRYING OUT A PILOT SURVEY BEFORE USING A QUESTIONNARE

  • assess time restrictions
  • check wording of questions in relation to response increasing accuracy
  • check suitabilty of location in terms of sample size/respondants
  • increase data set/coverage
  • risk assessment

JUSTIFY THE USE OF A MAP TO SHOW THE LOCATION OF AN INVESTIGATION

  • shows exact locations/accuracy
  • shows contours and land use
  • shows everything in relation (spatial)/shows (basic) positions of certain features of particular interest to the observer
  • can annotate and highlight features
  • highlight risks
  • help you pick location to investigate

STUDY FIG 2 A SKETCH MAP USED TO SHOW THE LOCATION OF A GEOGRAPHICAL INVESTIGATION IN AN INNER CITY AREA, COMMENT ON THE EFFECTIVENESS OF THIS SKETCH MAP IN LOCATING THE AREA

  • personal and possible to tailor to needs of individuals/study
  • title/key/scale
  • easy to construct
  • normally clear containing only key/relative features giving clarity
  • poor sketch map lacking integrity
  • no scale
  • no compass/direction
  • so no indication of proximity
  • no location/specific labels
  • no key
  • no title
  • so ineffective

EXPLAIN 2 ADVANTAGES OF USING SECONDARY DATA IN AN INVESTIGATION

  • readily available
  • already collected so saves time and effort on planning/conducting/repeating
  • more time for other aspects such as data analysis/presenting/conclusion/evaluation
  • economical since saves expenses of equipment and travel

OUTLINE THE VALUE OF CARRYING OUT A PILOT STUDY FOR A GEOGRAPHICAL INVESTIGATION

  • mini 'practise' version of full scale study
  • increases likelihood of of success in main since helps insure bring correct equipment (type) for data collection in real
  • helps highlight limitations/problems allowing to be overcome before hand e.g. equipment
  • help determine no of people needed
  • help determine time allocation (each task)
  • determine feasibilty of conducting larger scale to ensure wont be waste of time/money/resources

STUDY FIG 1 A FLOW LINE MAP (FLOW CHART) SHOWING THE RESULTS FROM AN INVESTIGATION INTO COMMUNTING FROM CHELSMFORD, COMMENT ON THE EFFECTVENESS OF IT IN SHOWING PATTERNS

  • helps to show movement (patterns) i.e. different volumes of traffic from different small settlements into one big settlement/variations in volume of traffic in an urban area
  • shows direction clearly
  • easy to follow and read
  • spacial
  • direction clearly shown
  • helps show data in proportion to each other
  • basic/oversimplified
  • not easy to read values
  • no indication of distance
  • no orientation
  • some places combined
  • no date or time of day

STUDY FIG 3 A MAP THAT SHOWS THE RESUKTS OF A POPULATION SURVEY IN A RURAL AREA, COMMENT ON THE EFFECTIVENESS OF THE METHOD OF DATA PRESENTATION

  • simplistic
  • no location/place names
  • no boundary labels
  • no source/census
  • no title
  • key not clear "5 people"
  • easily visible distribution
  • scale bar/compass bearing helps make it spacial
  • quick and simple to draw
  • visual
  • spacially shows distribution pattern

EVALUATE THE USE OF COLOUR IN DATA PRESENTATION

  • visually exciting drawing attention
  • helps show patterns
  • compare/contrast/clarity
  • show variables
  • colourblindness
  • may carry meanings i.e. blue for water or red for danger skewering reading or interpretation
  • some colours overpresented i.e. red
  • colour make be hard to tell apart esp if shading used

SUGGEST 2 ADVANTAGES OF USING THIS TECHNIQUE FOR SHOWING SUCH DATA (SKETCH MAP)

  • helps show locations in relation to one another so spacial
  • easy to read and understand
  • helps us understand patterns e.g. temp with increasing distance from building
  • isotherm lines used which are easy to read and easily identifiable

EXPLAIN WHY ANOMOLIES OFTEN OCCUR IN DATA COLLECTED FROM A GEOGRAPHICAL INVESTIGATION

  • human error/nature
  • lack of team work
  • misinterpretation of equipment/results
  • wrong equpiments (fails/faulty)
  • mininterpretation of instructions
  • carelessness
  • diffcult to get somewhere
  • poor weather
  • lack of knowledge e.g. cannot identify all plant species and some look similar
  • anomolies may be norm and model/concept flawed

STUDY FIG 2 A CONCLUSION BY A STUDENT FOR A GEOGRAPHICAL INVESTIGATION INTO THE RELATIONSHIP BETWEEN ROCK TYPE AND LAND USE, COMMENT ON THE EFFECTIVNESS AS A CONCLUSION

  • conc should be short para and sum up main findings
  • ref back to main findings and if evidence supports or not
  • ask if fits theory/model which its based up on
  • links to hypothesis and whether it relates and accept or not
  • doesnt pick up evidence
  • too simplistic e.g. more to soil type than rock type

EVAUATE THE USE OF SPEARMANS RANK CORRELATION COEFFICIENT TO TEST THE RELATIONSHIP BETWEEN 2 SETS OF DATA

  • easy to calculate
  • ranks order which avoids including anomolies
  • significane/strength of answer
  • can give direction of relationship
  • easy to make errros since so many stages involved
  • avoids extreme values
  • explains correlation
  • needs a min of 7 values
  • easy to make meaningless correlations

STUDY FIG 1 A PHOTT OF AN AREA IN WHICH A GEOGRAPHICAL INVESTIGATION IS TO BE UNDERTAKEN, STATE AND EXPLAIN USING EVIDENCE FROM THE PHOTO THE POSSIBLE RISKS TO THE PEOPLE CARRYING OUT THE INVESTIGATION

  • risk of drowning in river which flows through middle
  • person could trip and fall in and/or hit head on bed and become unconcious consequently drowning
  • large dump of stinging nettles in foreground so people get stung
  • made worse id person has allergies
  • 3 of trees on far side of river dead and therefore unstable
  • could fall on someone and/or if someone climbs then collapse causing injury
  • fence along west side looks old and unstable meaning it could collapse

EVALUATE THE USE OF PROPORTIONAL SYMBOLS TO SHOW DATA ON A MAP

  • can represent any size of data
  • obvious scale can also mean data can be seen in proportion to other data allowing patterns/theories to be seen
  • data can clearly be analysed
  • parts of map (detail/info) obscured by symbol
  • the larger the symbol the more area covered and the more map detail lost and therefore is ineffective
  • issue of where to place symbols on map
  • hard to tell if been placed at area where data collected or at points between making them ineffective

STUDY FIG 2 A LAND USE MAP SHOWING THE SAMPLING POINTS PLANNED FOR A GROGRAPHICAL INVESTIGATION, STATE AND JUSTIFY A HYPOTHESIS THAT WOULD BE APPROPRIATE FOR INVESTIGATION IN THIS AREA

  • 'the effect of land use on the diversity of species in this area'
  • bcos good range of land uses to study i.e. moorland/woodland/farmland/mosh
  • and theres also a good spread of sample points over these land use areas
  • SMART
  • all sites accessible meaning achievable
  • within travelling distance of each other meaning timed
  • large no of sample points would allow accurate average to be calculated
  • land uses naturally very different so species diversity likely to differ between them resulting in interesting and noticable change
  • has clear and strong geographical theory as basis
