lab - significant figures

Recommended Posts

Are we supposed to maintain significant figures when presenting raw data or is that only in calculations? Because readings for different measurement thingies (time vs. distance) have different degrees of uncertainty...

isn't this very confusing?

when presenting your collected data, the number of decimal place must be the same with the uncertainty.

for + and - calculations, the number of decimal place must follow the original data

for x and / calculations, the number of sig fig must follow the lowest number of sf of the original data.

all the %age uncertainty must be in 1 sf.
