GRAPH INTERPRETATION (WRITING TASK 1)
1. Examine
ALL the information on the graph.
- Identify the type of graph used
- Read the TITLE . The TITLE briefly describes the data represented in the graph.
- Read the footer or summary of the graph if included.
- Read the labels of the axes.
- X axis - the independent or manipulated variable
- Y axis - the dependent or responding variable
- Read the units of the axes. Ensure you know the quantity measured and the multiple or submultiple of the units used. Understanding the units used helps you to quantify relationships between variables.
- Read the scales of the axes.. Is the range a small or large one? Many students take in the shape of the graph without first considering the scale. This of course leads to erroneous conclusions.
- Examine the symbols and the Key/Legend used. Sometimes the curves or columns are labelled.
2. Observe
and describe patterns in the data.
- Patterns – LEFT TO RIGHT; TOP TO BOTTOM; BOTTOM TO TOP; RIGHT TO LEFT
- You shouldn’t write your opinion
- Pay attention to patterns and detail. Compare interrelating graphs.
3. Interpret
the Graph (Introduction, Overview, Body/Interpretation)
(NOTE: Don’t copy
phrases from the instructions as this will not be assessed. Use your own
words.)
- Introduction - A sentence describing what the graph / table shows (broad description of important trends shown)
·
Usually, the standard opening sentences to
introduce your report is “The graph
shows the…
- Overview - A statement which sums up the data / trends.
- Body - Description of the data. It may not be possible to describe all the data as there may be too much data presented. Describe the relevant and most important parts. If there is more than one graph / chart, describe any comparisons or trends that can be made out.
(NOTE: Avoid all
informal ways of writing. There are some rules of writing you should
follow. For example: no abbreviations, no 1st and 2nd pronoun or possessive (I,
you, me, my, your.)
