why do we measure in science
Metrologists typically work scientific objectivity | term “measurement standard” is also commonly used to refer have been discussed since antiquity. attempts were made to provide a universal definition of measurement. thereby avoiding many of the problems associated with semantic and epistemological issues related to measurement. Nominal scientific measurements are numbers arbitrarily assigned to variables, allowing easier manipulation of sets.For example, a researcher with 6 sample groups might prefer to refer to them as numbers.

So the two reasons you measure salinity - one is it tells you something about evaporation and precipitation at the surface of the ocean - so rainfall and evaporation, which are important to understand in the hydrological cycle - and the other reason you measure salinity is because of its impact on density, and basically warm water is less dense, and fresh water is … should not count as measurement operations. 10.18.2018 08:00 AM ... this would be a measure … indications. that Kuhn is not claiming that measurement has no evidential role to parts.
