Understanding Experimental Error - Las Positas College


One type of measurement uncertainty is due to instrumental resolution. If you are trying to measure the length of a piece of string, the precision of your length measurement depends on what type of ruler you use to measure the length. The smaller the tick marks on your ruler, the more precise your measurement.

detection capability of a measurement system, and is also reported in units of counts. The minimum detectable concentration (MDA) is the LD in counts multiplied by an appropriate conversion factor to give units consistent with a required measurement, such as Bq/cm2 or Bq/m3. MDA is the lowest activity value that can be achieved
