MAX 2 Uncertainty in one/each reading is 1 mm 1 OR The measurement involves making two readings / there are two uncertainties (to be considered) in this measurement 1 Difficulty / uncert ... ainty in locating (exact) position of (centre of) spot 2 Or Difficulty / uncertainty in lining up the (centre of the) spot with a graduation on the ruler 2 Or Difficulty / uncertainty in locating the position of A / B 2 the uncertainties from two (readings) are added 3 Allow the uncertainty in (reading) the position of a spot is 1 mm. 1 Owtte Do not allow: because the smallest division is 1 mm hard to see measurements to less than 1 mm (need to link to position of spot (or A or B) “because of both sides of the ruler” on its own “ruler slightly misaligned” too vague insufficient includes: uncertainty doubles uncertainty is twice the smallest division Random error or human error or error without further detail. However: The uncertainty doubles because there are two readings scores MP1 Also: The uncertainty doubles because there are two readings with identical uncertainties would score 2 marks. Mention of range of repeated measurements÷2 is not applicable in this case. [Show More]
