3. Graphs

Question 1

bipolar analysis - what does it show, and how effective is it at doing so (pos/neg)

Answer 1

large data on small space - good for big data sets
patterns easily identified
data must be in form of numbers that goes on a number line
needs lots of data to make

Question 2

dispersion diagram - what does it show, and how effective is it at doing so (pos/neg)

Answer 2

easily understood - aids comprehension so better analysed
anomalies are shown clearly
can compare more than one graph together
Shows the spread from the mean -
gives an indication of the reliability of the data?

Question 3

kite diagram - what does it show, and how effective is it at doing so (pos/neg)

Answer 3

shows changes over time - allows easy comparison
visually clear - aids comprehension
can be compared to each other - allows easier testing for hypothesis

Question 4

logarithmic graph - what does it show, and how effective is it at doing so (pos/neg)

Answer 4

shows a large range of data than a linear scale does
shows a large amount of data in small values - can hold more detail
zero is not plotted
smaller values are not always clear - can be read wrong
can be difficult to accurately plot values

Question 5

polar graph - what does it show, and how effective is it at doing so (pos/neg)

Answer 5

Good for corries, vegetation retail info and slopes - circular graphs and show variation over time - uses compass bearings
Rose diagram - specifically for wind
-
patterns are easily identified - lots of data can be compared
good for directional data - which most other graphs are not
used for a limited type of data
hard to spot anomalies - more difficult to analysis (trends)
doesn’t use specific data numbers

Question 6

system diagram - what does it show, and how effective is it at doing so (pos/neg)

Answer 6

clear 3D representation of area - visualises key data clearly
demonstrates the relationship between various stages
is an important tool for planning and laying out a process - easy to draw
requires lots of planning to include all stages correctly - can take long time to produce

Question 7

scatter graph - what does it show, and how effective is it at doing so (pos/neg)

Answer 7

large amount of data can be plotted on small space
patterns easily identified and analysed
anomalies in data easily identified
can only be used to display two variables
can easily make mistake plotting data - not always reliable

Question 8

triangular graph - what does it show, and how effective is it at doing so (pos/neg)

Answer 8

large amount of data is shown
uses clear plots
confusing to draw
can be difficult to read
