what are 2 other way to make sure that you are making an accurate and precise measurement? Type your answer in the boxes below.

to find if it is precise is to find the difference. accurate is the quality or state of being correct or precise.

Explanation:

Accuracy is how close a value is to its true value. an example is how close an arrow gets to the bull's-eye center. Precision is how repeatable a measurement is. An example is how close a second arrow is to the first one (regardless of whether either is near the mark).

find the average of your data then subtract each measurement this gives you a table of deviations. then average the deviations

Explanation:

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
