Advantages -
it is easy to understand
can easily compare two or three data sets
Disadvantages - graph categories Can be reordered to emphasize certain effects
only use with separate data
Line Graph
Advantages -
can compare multiple data sets easily
data can be inferred from graph line
Disadvantages -
use only with continuous date
Circle Graph
Advantages -
visually appealing
shows the total for each category
Disadvantages -
the data is not exact
hard to compare 2 data sets
the total is unknown unless specified
Pictograph
Advantages -
easy to read
visually appealing
Disadvantages -
very simplistic
icons must be the same size
Double Bar Graph
Advantages -
best for comparing 2 data sets
Disadvantages -
it could confuse people
Misrepresentation -
break in the y axis
if bars are bigger than others
if pictures on the pictograph are not the same size
2a) I would use a bar graph and a line graph
2b) I would continue selling them because on a line graph the sales are going up
4a) I would choose the line graph
4b)
