True or false? All droppers all calibrated to deliver standardized drops of equal amounts regardless of the dropper used.

Final answer:

The statement is false as not all droppers are calibrated to deliver standardized drops of equal amounts. Accuracy and precision in measurement vary between droppers, meaning they could be consistent (precision).

Step-by-step explanation:

The statement is false; not all droppers are calibrated to deliver standardized drops of equal amounts regardless of the dropper used. This can be understood by examining the concepts of accuracy and precision in the context of measurement. In a pharmaceutical setting, for instance, if a quality control chemist checks the performance of different dispensers meant to dispense a certain volume, she might find varying results.

Dispenser #1 might be precise, meaning the dispensed volumes are consistent with each other, but not accurate, as they do not match the target volume. Dispenser #2 could offer better accuracy, with dispensed volumes closer to the target, but poor precision, indicated by greater variation. Only dispenser #3 might achieve the necessary standard, being both accurate and precise, delivering volumes within a very tight range of the target volume.

This scenario highlights that different droppers, like dispensers in the example, can have varying levels of accuracy and precision. Therefore, unless specifically calibrated, droppers cannot be assumed to deliver equal amounts.
