When one chases behind a normal particle (e.g., an airplane) or moves in the opposite direction toward it, one certainly will measure very different speeds of the airplane relative to oneself.
However, it should be noted that surveys and observational studies often measure very different aspects of reality.
Secondary data sources measured very different aspects of the local environment that could be used to derive a range of environmental measures if validated properly.
Hence, the two preservation statistics offer a largely consistent picture of module preservation, even though they measure very different quantities.
These quantities have some similarities but they measure very different things and it is important that they should not be confused.
These two ways of looking at the question measure very different things: for instance, even a large increase in the number of accessible pathways may not greatly alter the distribution of probabilities among accessible pathways, if many new pathways have very small probabilities.
Some correlations between domains in the SGRQ and CCQ were not significant, but these domains measure very different aspects of health status.
Measures of flight distances can thus quantify very different behaviors of bees.
The ESA Swarm mission to identify and measure very accurately the different magnetic signals that arise in the Earth's core, mantle, crust, oceans, ionosphere and magnetosphere, which together form the magnetic field around the Earth, has increased interest in magnetic data collected on the surface of the Earth at observatories.
One review [ 11] calculated mean differences instead of standardized mean differences, although the outcomes were measured on very different scales.
