Precise question,,help?
Could you have determined which device was more precise by making a single measurement??? When it comes to volumetric pipet, graduated cylinder, or beaker???
I would say you couldn't and multiple trials would be needed to know...but what do y'all think??
And one more q???
Do y'all think the change of temperature water during the lab period would have any affect on accuracy/precision ???
Thank you and please comment, I need feedback

Your reasoning is correct, precision requires more than one measurement. If you had three (or more) trials you could calculate the standard deviation and see how closely your measurements were grouped together. If you had only one data point you could measure accuracy, but not your precision.
As the temperature of water changes so does its density. This can affect your accuracy and precision depending on the calculation.
