graphical representation cons

Question 1

Systems diagrams

Answer 1

can be complicated
time consuming and confusing to draw

Question 2

logarithmic diagrams

Answer 2

can be complicated to draw scale and read
if changes are small this can be hard to read of graphs’ particularly with bigger numbers.
time consuming to draw.

Question 3

Polar graphs

Answer 3

can be hard to draw a suitable scale
hard to draw concentric circles
time consuming to draw if no template
can become cluttered in the middle if lots of directions

Question 4

Scattergraphs

Answer 4

depending on values it can be hard to see a line of best fit
further testing is always needed sometimes a relationship is there just not very visible.
mistakes can be made if there is a large number of points close together

Question 5

Dispersion diagrams

Answer 5

Can become a very crowded diagram
the spread or range doesnt tell you everything about a set of data
data must be in a form that can be placed on a number line

Question 6

Bipolar analysis

Answer 6

Lots of crossovers can cause it to become hard to read and too crowded.
often better to add up totals and put them in other graphs.
using +2 and -2 makes it clearer on the bipolar but makes adding up totals a bit more complex.
Often the data gathered is subjective to opinion.
if too many areas are compared it can become very clustered.

Question 7

Triangular graphs

Answer 7

Complicated to plot
Complicated to read
Time consuming to plot and read
