LO 2:
COLLECT SAMPLES

2. Sampling
-is one of the most important factors which
determines the accuracy of your research/survey
result.
-is a tool that is used to indicate how much
data to collect and how often it should be
collected. This tool defines the samples to take in
order to quantify a system, process, issue or
problem.

3. Sampling plan
• is detailed outline of
measurements to be taken which
includes the objectives, outline of
which measurements will be taken
at what time, on which material, in
what manner, and by whom.

4. Steps in the sampling plan
1. Identify the parameters to be measured, the range
of possible values, and the required resolution
2. Design a sampling scheme that give details on how
and when samples be taken
3. Select sample sizes
4. Good personal hygiene
5. Design data storage formats
6. Assign roles and responsibilities

5. Random Sampling
•A random sampling is a
sampling procedure where
every element has an equal
chance of getting selected to
be part of a sample.

6. Stratified Sampling
•This technique divides the elements of
the population into small subgroups
(strata) based on the similarity in such a
way that the elements within the group
are homogeneous and heterogeneous
among the other subgroups formed.

7. Systematic Sampling
•In here the selection of elements is
systematic and not random except the
first element. Elements of a sample are
chosen at regular intervals of
population. All the elements are put
together in a sequence first where each
element has the equal chance of being
selected.

8. Convenience Sampling
•This method is used when
the availability of sample is
rare and also costly. So,
based on the convenience
samples are selected.

9. Cluster Sampling
•A sampling is accomplished
by dividing the population
into groups – usually
geographically/ location.

10. Sample Handling
•Comprises the preparation
of the samples and
recording its information
or data.

11. GMP
•Good Manufacturing Practices (GMP)
are systems of processes, procedures,
and documentations that help ensure
that products are consistently
produced and controlled according to
quality standards.
