Any experimental work that forms part of a physics extended essay should be adequately described to allow the workto be repeated by others, who should achieve similar outcomes and conclusions. Particular care should be taken with data obtained through secondary sources. For data-based essays, the location and reliability of the sources needed should be considered at the start of the planning stage. Students must scrutinize such data and the experimental design with the same care that they would apply to data that they have collected themselves. A careful scrutiny of research procedures could reveal serious flaws in experimental design or in data collection that invalidate the results in whole or in part, or at least limit the interpretation.

P. Dowling – Physics Extended Essay
If you are new to the IB then you might not know this yet but to get an A with a physics extended essay is almost impossible, the statistics are certainly not encouraging.
