A

RA 10657

25
Q

Refers to a single pile of a material. Not in the form of separate permanently
identifiable units.

A

Bulk material

26
Q

Comprised of identifiable units, which may be assigned numbers.

A

Packaged material

27
Q

Bulk materials that are partially packaged into smaller units, such as bags or drums.

A

Segments

28
Q

A quantity of the material transferred on one occasion and covered by a single
set of shipping documents.

A

Consignment

29
Q

Refers to quantity of material which is assumed to represent a single population for sampling purposes.

A

Lot

30
Q

Refers to quantity of material which is known or assumed to have been produced under
uniform conditions.

A

Batch

31
Q

Are portions of the material obtained from the lot/batch by using a sampling device.

A

lncrements

32
Q

Result of combined increments.

A

Primary or gross sample

33
Q

Results from a number of primary samples combined and mixed.

A

Composite or aggregate

34
Q

A portion of material delivered to the laboratory for analysis. Obtained from primary or composite sample by a series of division and reduction processes

A

Laboratory sample

35
Q

Refers to a quantity of material that is actually submitted for analysis. Technically,
it is called as analytical portion.

A

Test portion

36
Q

Samples with characteristics the same as that of parent material.

A

Representative Samples

37
Q

Obtained by choosing certain portions of the material possessing the desired characteristics to be analyzed

A

Selective Samples

38
Q

Obtained by using a random sampling plan that generates data for the purpose of statistical analyses

A

Random Samples

39
Q

Two or more portions of the material collected at the same time.

A

Composite Samples

40
Q

Performed when statistical evaluation is needed to be employed on the set of data.

A

Probability Sampling or Random Sampling

41
Q

Any sample has an equal chance of selection.

A

Simple Random Sampling

42
Q

The lot is subdivided/stratified where a simple random sample
is selected from each stratum.

A

Stratified Random Sampling

43
Q

The first sample is selected randomly and then subsequent
samples are taken according to a previously arranged interval.

A

Systematic Random Sampling

44
Q

Performed when a representative sample is not appropriate, hence, results in selective samples.

A

Non-probability Sampling

45
Q

Knowledge about the material is required to select the desired specific samples.

A

Judgement Sampling

46
Q

The materials are subdivided into groups where a sample is selected from each group.

A

Quota Sampling

47
Q

Performed when selecting a sample depends on its availability and accessibility.

A

Convenience Sampling

48
Q

Involves selection of a sample from material which does not consist of discrete, identifiable or constant units.

A

Bulk Sampling

49
Q

Involves the use of a predetermined sampling plan to determine if the batch
of materials meets the defined criteria for acceptance.

A

Acceptance Sampling
