Types of data
Discrete data- data with distinct separate parts
Ordinal data- data that has an order
Continuous data- data where there are no breaks but instead something
happens continuously.
Areal data- data that applies to an area rather than a point or an individual
Time series data- data where something occurs at intervals
Period data- data where a phenomenon repeats it's self at intervals
Factors to consider when selecting a technique to present your data
factors Comment
Scale/interval If the scale is too big it will hide patterns
If the scale is too small, it will take too long to make
and could produce complex patterns that are hard to
Figures have a clear scale with no overlapping values
Scale always starts at 0
location Where should the figure be placed to represent the area it
applies to best? Make sure comparative diagrams are the same
Size of symbol Symbols shouldn't be too large or else they can overlap or hide
information on the map. They mustn't be too small or else they
can be hard to see or may be read incorrectly
shading Should always get darker as the value increases, white will
apply to their being no data. The shade should always be of the
same colour.
colour Colour should be avoided as it is difficult to compare colours.
However, colour can be useful when comparing patterns
lettering Varies in alignment, size, spacing and style. Shouldn't obscure
data and should be able to be reads easily, similar sizes should
be used on one technique of presenting data
dimension 3D can cope with higher values, but the value is proportional
to its value so this involves careful calculation and it may
mislead visually by looking less than it actually is
key All maps and diagrams should have a clear key, and should be
located in a clear location on your map or diagram
Legend or All diagrams and maps should have a title and figure number
scale All maps should have a scale
