Data Collection and Presentation, Aspect 2

By Wednesday, November 3, 2010 , , , , 0

Today we will consider DCP, aspect 2. This aspect deals with the processing of the raw data collected in aspect 1.

It should involve an ‘IB CHEMISTRY type’ calculation – it should not be simply calculating averages or calculating 1 / t (for a rate).  The calculation should be demanding enough that an IB Chemist should be able to carry it out (but not another student following another IB subject).

If the students carries out the processing of the data correctly, award the ‘c’. If there are minor mistakes, award the ‘p’ and i f there are major mistakes, the ‘n’.

Tomorrow, aspect 3 which deals with significant figures and uncertainties in calculations.
