What are the 'limits of experimental accuracy' - Physics

[Fayadh Ahmed]

The title says it all, I think. It's there in almost every markscheme. So what are the limits?

 

[Shizza Jalil]

For instance, the actual answer for a question is x, however your calculated answer is x+0.02. Although not the exact same thing, it would still be considered correct, since the result lies in the limits of experimental accuracy. As in, the results are close enough to be accepted.

 

[Fayadh Ahmed]

Yeah, I figured as much. I was just wondering what are the limit's to be considered accurate? For example x+0.5 would that be considered an accurate answer?

 

[Catherine7532]

so in justification if v just write 'within limits of experimental accuracy the statement is true' will it be marked correct???? or do v need to explain the justification

 

[Shizza Jalil]

Fayadh Ahmed How much comes under the 'experimental accuracy' tag really depends on the specific question you're working on. :/

Catherine7532 Yes, that line is enough to score the marks, in most cases.
