Data Interpretation & Analysis 1
Review the graph below and explain your findings.
Average Candidate Response
This is a speed-time graph which shows an object accelerate, maintain a constant speed and then decelerate to a stationary state.
Excellent Candidate Response
Excellent candidates will use the 'BlackStone Tutors Six Point Approach for Data Analysis'
This is a speed-time graph for an unspecified object. On the ‘x’ axis, is time measured in seconds, with speed in metres/second recorded on the ‘y’ axis. The object is initially stationary at time 0, thereafter accelerating at a constant 1.6 m/s² for 10 seconds until it reaches the constant speed of 16m/s. The object maintains this speed for 10 seconds, before decelerating at 3.2 m/s² for 5 seconds until it is once again stationary at time 25 seconds. The area under the graph represents the total distance travelled, which in this case is 240 metres. Given the speeds stated, the object may represent a bicycle, a fast runner or a slow vehicle.
There are no anomalies of note and an obvious source for the graph cannot be seen. It would be beneficial if the graph had a title as well as a reference source.

- Data Title (if present)
- 'x' axis and 'y' axis
- Graphical/tabular progression shown
- Physiological correlation (How can this pattern be explained biologically?)
- Anomalies/additional information of note
- Critical analysis of data/data source
