A point of reference from which measurements or estimates may be made is often called a benchmark

What is datum plate?
Alevel metal plate attached to the tank shell or bottom and located directly under the gauging reference point to provide a fixed contact surface from which liquid depth measurement can be made.
Why did the feline make a beeline for the tree line?
The feline made a beeline for the tree line to act as a point of reference.
Does the displacement arrow depend on the choice of reference point?
Yes and no.Some use "displacement" only to describe a change in the position of an object from some initial starting point to some ending point. That is, there is a distinction between "position" and "displacement." The position would be defined relative to a reference point. In that case the arrow depends only on where the particle was and where it ended up and the reference point does not matter.Others use a definition for displacement which describes the difference between an object's position and a fixed reference point. That is, how far an object is displaced from a certain point even if the object had never been at that point. A distinction between position and displacement is not made. For this latter definition, the choice of reference point will make a difference in the direction of the arrow.In physics problems one usually only cares about the changes in position (and velocity, etc) and the choice of reference point will not affect these.
When should relative measures of dispersion be used?
They may be used-with considerable caution-when the measurements in the various populations being compared were made in different units. Dividing the dispersion estimates by the location estimates eliminates eliminates the differences attributable to differences in measuring units. However, caution is advised because the measurement methods may have differed in the various populations, giving rise to differences in the dispersion estimates having nothing to do with dispersion in the populations. In other words, there could well be differing levels of measurement error across populations.

An indirect measurement of the speed of molecules is made with a thermometer.
Why is the reference point important in order to describe motion?
You move in relation to something, for instance, if you take the planet Earth as a reference, then we're not moving, even if you walk around. However, we're moving in relation to the sun because we're on a planet that is. If you drive a car, you're not moving in relation to the seat you're sitting on, but you are moving in relation to sign posts that you leave behind.
What is horizontal measurement?
The horizontal measurement refers to the measurement that is made along the X-axis. The horizontal measurement is usually one dimensional.
Why was it important for romes laws to be written down?
Because considering the size and population that the laws of Rome covered there could never be agreement on the the law if there was no central reference point to refer to when a legal decision had to be made.
Why does electricity earth it self?
The mass of the Earth is the reference point. All man-made generators are grounded to the Earth. Lightning just evens itself out.
What is an intermediate sight in surveying?
On a typical boundary survey the instrument is sighted on a point from which angles will be measured, the backsight, and the next survey point where the instrument will be set up to continue the survey around the property, the foresight. Intermediate foresights, often "called sideshots," are points to which measurements are made other than the foresight or backsight. For example, a survey instrument is set up over a point. The horizontal angle on the instrument is set on 0 while sighting on a backsight point that may be a couple hundred feet away. A measurement will be taken to the foresight point which may also be a couple hundred feet away. There may be a survey marker near the point where the instrument is set up to which a measurement needs to be made. This measurement is called an intermediate foresight or a sideshot.
An observation made with measurement?
Quantitative
How do you write a rate of measurement?
A rate of measurement is the number of measurements made per unit of time.
