It is important to record your data with all the decimals provided by the instruments even if they are zero because it increases the accuracy of the measurement.
<h3>What is accuracy in experimentation?</h3>
Accuracy refers to the ability to take correct measurement values during a specific experiment and/or observational procedure.
Accuracy is a fundamental issue in data analysis and helps to obtain conclusions from a given experimental procedure.
In conclusion, it is important to record your data with all the decimals provided by the instruments even if they are zero because it increases the accuracy of the measurement.
