  • 1

    what are the two types of measurements in surveying?

    Directly and Indirectly

  • 2

    a type of measurement which is the comparison of the measured quantity with a standard measuring units.

    Direct Measurements

  • 3

    a type of measurement which the observed value is determined by its relationship to some other known values.

    Indirect Measurements

  • 4

    it is the process of determining the extent size or dimensions of a particular quantity in comparison to a given standard

    Measurement

  • 5

    measurements are usually concerned on:

    angles elevations times lines areas volume

  • 6

    __________ are never exact and they will always be imperfect no matter how carefully made

    Measurements

  • 7

    It is commonly known as the metric system world's most widely used.

  • 8

    What are the 4 unit systems in various field applications?

    circular or natural system, sexagesimal system, centesimal system, military system

  • 9

    SI unit for angles measured in radiance

  • 10

    english unit system for angles which is measured in terms of degrees

    sexagesimal system

  • 15

    mistakes are also called as ______.

    blunders

  • 16

  • 18

    name the 5 types of errors

  • 23

    an error caused by inability of the individual to make exact observations due to the limit of human sight.

    personal error

  • 24

    systematic error is also known as ______.

    biases

  • 25

    it indicates how close a given measurement is

    accuracy

  • 26

    it refers to the degree of consistency of a group of observations

    precision

  • 27

    by mathematical definition, it is the number of favorable events divided by total number of events

    probability

  • 28

    it is the mean of an infinite number of observations.

    most probable value (mpv)

  • 29

    it is a set of data refers to the quantity which has more chances of being true than any other available data.

    most probable value (mpv)

  • 30

    if we have a group of repeated measurements performed under similar conditions then the mpv is the ________ or the average of all the measurements.

    arithmetic mean

  • 31

    it is also called as deviation it is the difference between the MPV in any observed quantity

    residual

  • 32

    residual is also called as ______.

    deviation

  • 33

    it is a measure of the amount of variation or dispersion on a set of data in relation to its mean.

    standard deviation (sx)

  • 34

    what do you measure in a standard deviation?

    variation or dispersion on a set of data

  • 35

    it is equal to the square or the standard deviation.

    variance (sx²)

  • 36

    _________ and _______ are used to measure the variability or dispersion on a set of data but their units differ.
