Analysis Aspect 1 Aspect 2 Aspect 3 Aspect 4 Raw Data Data Processing Measurement Uncertainty Interpretation of Data 5-6 marks Sufficient relevant quantitative and qualitative raw data that could support a detailed and valid conclusion to the research question. Appropriate and sufficient data processing is carried out with the accuracy required to enable a conclusion to the research question to be drawn that is fully consistent with the experimental data. Evidence of full and appropriate consideration of the impact of measurement uncertainty on the analysis. Processed data is correctly interpreted so that a completely valid and detailed conclusion to the research question can be deduced. 3-4 marks Relevant but incomplete quantitative and qualitative raw data that could support a simple or partially valid conclusion to the research question. Appropriate and sufficient data processing is carried out that could lead to a broadly valid conclusion but there are significant inaccuracies and inconsistencies in the processing. Evidence of some consideration of the impact of measurement uncertainty on the analysis. Processed data is interpreted so that a broadly valid but incomplete or limited conclusion to the research question can be deduced. 1-2 marks Insufficient relevant raw data to support a valid conclusion to Some basic data processing is carried out but is either too inaccurate or too insufficient to Evidence of little consideration of the impact of measurement Processed data is incorrectly or insufficiently interpreted so that the conclusion is
