This criterion assesses the extent to which the student’s report provides evidence that the student has recorded, processed and presented the data in ways that are relevant to the research question.
| Mark | Descriptor |
| 0 | The student's report does not reach a standard described by the descriptors below. |
| 1-2 | • The recording and processing of the data is communicated but is neither clear nor precise. • The recording and processing of data shows limited evidence of the consideration of uncertainties. • Some processing of data relevant to addressing the research question is carried out but with major omissions, inaccuracies or inconsistencies. |
| 3-4 | • The communication of the recording and processing of the data is either clear or precise. • The recording and processing of data shows evidence of a consideration of uncertainties but with some significant omissions or inaccuracies. • The processing of data relevant to addressing the research question is carried out but with some significant omissions, inaccuracies or inconsistencies. |
| 5-6 | • The communication of the recording and processing of the data is both clear and precise. • The recording and processing of data shows evidence of an appropriate consideration of uncertainties. • The processing of data relevant to addressing the research question is carried out appropriately and accurately. |
Clarifications for data analysis
Data refers to quantitative data or a combination of both quantitative and qualitative data.
Communication
- Clear communication means that the method of processing can be understood easily.
- Precise communication refers to following conventions correctly, such as those relating to the annotation of graphs and tables or the use of units, decimal places and significant figures.
- Consideration of uncertainties is subject specific and further guidance is given in the Chemistry teacher support material.
- Major omissions, inaccuracies or inconsistencies impede the possibility of drawing a valid conclusion that addresses the research question.
- Significant omissions, inaccuracies or inconsistencies allow the possibility of drawing a conclusion that addresses the research question, but with some limit to its validity or detail.
