Controlled assessment High level presentation made easy!

Accuracy and completeness

The course requirements Types of more complex presentation skills that students could use to access Level 3 The skill itself is just part of the requirement. Completeness, accuracy and appropriateness must also be assessed. Presentation skills that have been used at Level 3 in the past include: cross sections (do not exaggerate scales) proportional flow line maps isoline maps choropleth maps proportional flow line maps proportional symbols located on to base maps some statistical techniques (all working shown) scatter graphs very well annotated photographs and field sketches.

Presentation at an advanced level … is all about information and interpretation, and location Graphs do not necessarily speak for themselves Data in geography is always locational – it depends on where it is (that’s the geographical part of it!)

Advanced presentation Annotation of maps/images Easy! Make your comments relevant and highly descriptive Opportunity to interpret Opportunity to evaluate Some examples:

Complex? High level of congestion found here during rush hour times Traffic lights here have negligible effect on congestion on lower part of road

Complex? Extensive parking for customers: they can visit more than one major retailer in one visit Limited parking for patrons: just a stop and drop visit!

Inventive bar charts Multiple data sets? You can go from this…

Better?

OK – but how about this: LOCATE your data

Proportional bar chart…

Land use map? Good to show clustering of activity e.g. retail Shade in each plot to represent the land use Good for developing patterns But don’t forget the conventions…

Other map types Choropleth maps – could represent environmental quality survey scores for a range of areas Dot maps: frequency or location of a variable e.g. litter across a park

Flowline Arrows represent size of flow e.g. traffic count or pedestrian count 2pm on Saturday What can you see? Why? Example key =10 cars

Desire line Great for assessing the popularity or geographic reach of a function or place Work out the market area by taking an average of the distances – becomes the radius of the ring around the function

Isoline

Other types of graph Kite chart: how does this work? Star diagram

Some statistical techniques Spearman’s rank Tests the strength of a relationship between two variables Chi Squared measures how well the observed data matches up to what we would expect
