Observation Technique
7. Prior to doing the observation, it is important for the
researcher to ensure that the following conditions are met:
• The needed information must be observable or inferable from the behavior that
can be observed.
• The subject matter contains some sensitivity that needs detached observation.
• The behaviors of interest must be repetitive, frequent or profitable in some
manner.
• The behavior of interest must be of a relatively short duration.
8. Survey is the most preferred instrument for in
depth quantitative research.

9. In planning a survey, there are three important
concerns that one has to look into:
• Questionnaire Design
• Sampling Technique
10. Questionnaire
Design
• The questions, their totality, should be able to elicit all the necessary
information required in the research.
• Each question should be clear and definite
• Each questions should cover one topic at a time

• Each question should be translated into the dialect that the target
respondents are familiar with.
14. In simple random sampling technique, every item in
the population has an equal and likely chance of being
selected in the sample.

15. In a stratified sampling method, the total population is
divided into smaller groups to complete the sampling
process.
Stratified Sampling
𝑛 =
𝑛𝑜. 𝑜𝑓 𝑟𝑒𝑠𝑝𝑜𝑛𝑑𝑒𝑛𝑡 𝑖𝑛 𝑠𝑡𝑟𝑎𝑡𝑢𝑚
𝑡𝑜𝑡𝑎𝑙 𝑛𝑜. 𝑜𝑓 𝑝𝑜𝑝𝑢𝑙𝑎𝑡𝑖𝑜𝑛
× 𝑛𝑜. 𝑜𝑓 𝑠𝑎𝑚𝑝𝑙𝑒𝑠 𝑟𝑒𝑞𝑢𝑖𝑟𝑒𝑑
16. In the systematic sampling method, the items are selected from
the target population by selecting the random selection point and
selecting the other methods after a fixed sample interval.
Systematic Sampling
𝑘 =

𝑛
18. It refers to the technique that is resorted to “ when
it is difficult to estimate the population of the study
because they are mobile or transitory in a given
location.
Non-Probability Sampling
21. Convenience sampling is a non-probability sampling
technique where samples are selected from the population
only because they are conveniently available to the
researcher.
Convinience Sampling
22. Consecutive sampling technique gives the researcher a
chance to work with many topics and fine-tune his/her
research by collecting results that have vital insights
Consecutive Sampling
23. Quota sampling is defined as a non-probability sampling
method in which researchers create a sample involving
individuals that represent a population.
Quota Sampling
24. In the judgmental sampling method, researchers select the
samples based purely on the researcher’s knowledge and
credibility.
Judgmental Sampling
25. Snowball sampling or chain-referral sampling is defined as a
non-probability sampling technique in which the samples
have traits that are rare to find.
Snowball Sampling
27. Let us go to the steps in conducting a survey
Research:
• Develop the Research objectives.
• Determine your sample.
• Choose the interviewing methodology.
• Create your questionnaire.
• Pre-test the questionnaire.
• Conduct interviews and enter data.
• Analyze the data.
29. • Are there any special foods preferences, buying habits and ways of

what cultural and or historical factors brought these about.
