Introducing graphs

Table

Bar graph

Line graph

Pie chart

Flow chart

Maps

Features of Each Type of Graph

Table

large capacity (eg. 50 rows on a A4),

patterns not easily identified

suits nominal as well as numerical data

able to show cross-sectional & longitudinal data

Pie chart:

limited capacity

nominal & numerical data (%)

suits cross-sectional data unless used in series

30 items/variables

Bar graph /Line graph:

Similarities: large capacity; suit cross-sectional & longitudinal data; easy to identify patterns and trends

Differences: bar graphs better for discrete data; line graphs more for continuous data

Flow chart: for processes /procedures, usually sequential

Maps: multi-directional; locations & directions

Language features:

Flow chart: conjunctions describing sequence

Maps: words showing locations and directions

Some vocabulary (eg. ordinal) applies to most other graphs, eg. rank first, account for, a significant increase/decrease

Some vocabulary only for line graphs, eg. fluctuation, steady rise, plummet, soar
