1.      Context of the Experiment

...

A complete measurement can only be specified by taking the uncertainty into account, it can be displayed as where M is the average of or the one measurement and u is the uncertainty. The uncertainty can also be specified as a relative value, e.g. in percent of the measured value M. A measured value that has multiple decimal digits can show more digits than the uncertainty allows, therefore rounding to the last decimal digit of the uncertainty is common.
