What is the difference between direct and indirect measurement?

Direct is an exact measurement and indirect is an estimate.


What is the difference between direct and indirect measurement in surveying?

Direct Measurement: Apply the instrument directly to the unknown quantity. E.g. Taped distance, direction measured with a theodolite Indirect Measurement: Determined from its relationship to direct measurements. E.g. height difference determination in trigonometric leveling


What is the difference between sp02 and sa02?

Both are measurements of the saturation of hemoglobin with oxygen in arterial blood.The difference is how the measurement is taken SpO2 is an indirect measurement using a finger probe, ear sensor or similar device. SaO2 is a direct measurement using a blood sample such as an arterial blood gas analysis.


What are different types of linear measurement?

there are two types linears measurements 1)direct 2) indirect


How do we know we can use indirect measurements geometry ?

The idea is that you model a situation with similar triangles and then use proportions to find the missing measurement indirectly.


When is the indirect method appropriate and what are the benefits of using it?

Indirect measurement is a technique that uses proportions to find a measurement when direct measurement is not possible.


An indirect measurement of the speed of molecules is made with a?

An indirect measurement of the speed of molecules is made with a thermometer.


What is an indirect measure and why are such measures common in software metric works?

Indirect measurement is a measurement that is not obtained from a measurement tool; it is a technique that obtains a measurement when direct measurement is not possible. In software metrics work, indirect measures associate a measure to a feature of the object being measured. An example is basing quality on counting rejects. Indirect measures include functionality, quality, complexity, efficiency, reliability, and maintainability.


An indirect measurement of the speed of molecules is?

The temperature.


Temperature is an indirect measurement of?

The speed of molecules.


How are similar triangles useful for indirect measurement?

NO


What is indirect measurement and how is it useful?

When instead of measuring the specific thing directly you measure some other aspect of the event and from that figure out the actual value. Ex. Lets say that you need to find out the height of a tower, but that you can not measure it from top to bottom with a measuring tape. You can measure the shadow on the ground and with knowledge of the suns position and the angle of the shadow calculate the height of the tower.
