Validity and accuracy? (1 Viewer)

[chocolatelatte]

So I know that validity can be ensured/improved by controlling variables and having a control. Does accuracy of equipment impact validity (e.g. smaller gradations on a thermometer)? I know that accuracy can be improved by your choice of equipment but can validity be improved if you improve your accuracy?

THANKS

This is a bit more complicated, more accurate equipment will make your results more valid (if the method is valid) but it won't make the scientific method more valid because the method doesn't really consider equipment.
