Candidates must be able to process experimental results by:

• tabulating data using appropriate headings and units of measurement
• representing data as a scatter graph with suitable scales and labels
• sketching a line of best fit (straight or curved) to represent the trend observed in the data
• calculating average (mean) values
• identifying and eliminating rogue points
• commenting on the reproducibility of results where measurements have been repeated

The uncertainty associated with a measurement can be indicated in the form: measurement ± uncertainty.
