Presentation Transcript

  1. Introducing graphs Table Bar graph Line graph Pie chart Flow chart Maps

  2. Features of Each Type of Graph • patterns not easily identified Table large capacity (eg. 50 rows on a A4) suits nominal as well as numerical data able to show cross-sectional & longitudinal data • Pie chart • nominal & numerical data (%) • suits cross-sectional data unless used in series • limited capacity

  3. 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

  4. Flow chart: for processes /procedures, usually sequential Maps: multi-directional; locations & directions

  5. Language features: Flow chart: frequent use of conjunctions describing sequence Maps: use of vocab showing locations and directions • Some vocabulary only for line graphs, e.g. fluctuate, rise steadily, plummet, soar , hit a high/low, plateau, level off, decline gradually • Other vocabulary applicable to most graphs, e.g. rank first (ordinal), follow closely behind , account for, increase, decrease

  6. 3-Paragraph Schematic Structure Note: paragraphing not an IELTS requirement but for clarity.
