I'd recommend not to use the parallax error point cause some places they didn't accept it so b on the safe side
N in places of significant figures always write that we consider the least number of significant figured from the raw data

guys read this

Though this guy did mention this experiment abt pressure n I think it will b somewat similar cause the variants that r on the same time r usually simple.

They usually give a one or two mark qs that why u have selected these many s.f. In ur reading so my sir told me that we always consider the least number of s.f. from the raw data though their can b a range of s.f. in ur raw data. That's all I know :p

i have doubt like when measuring by a metre ruler it measures nearest to 0.1m right? as the smallest reading that can be obtained is 0.1m right? so uncertainity would be 0.1 if only taking one reading only?
and what the difference between absoulte eror and the normal one i remember absoulte one was half the smallest reading is it correct? an we use it for what?
thanks guys

See absolute uncertainty is the range of value we are unsure about so for a ruler least count is 0.1 we Unsure that the value for eg is 23.4 so with this uncertainty it can be either 23.3 or 23.5
