This includes identifying equipment to use for a measurement and recording the measurement to the correct number of significant figures. Scientists generally measure liquids using volume measurements and solids using mass measurements.Controls are needed to make sure the experiment worked. if there are no positive controls and the sample is negative, we can't know if the sample was truly negative or if the assay process didn't work. Conversely, without a negative control, there is no way of knowing if all samples (positive or not) would have given a positive result
