Elements and Performance Criteria
- Read and construct graphs from given or determined data
- Complex information is extracted from graphical representation.
- Data is analysed with respect to emerging trends.
- Graphs are constructed as required from data and drawn with respect to scale and accepted method.
- Significant features of graphical representation are understood such as limit lines, gradients (straight line graphs), intercepts, maximum and minimum values.
- A wide variety of graphs are constructed as required including histograms, control charts, straight line graphs and parabolic graphs.
- Perform basic statistical calculations
