Sampling Techniques & Pilot Studies
HMPYC 8
in Quantitative Research
, ➢ 1. Introduction:
• The pilot study is one way in which you can orientate yourself as a prospective researcher to the project you
mind.
• You should try to avoid the temptation to skip the pilot phase, as little efforts can greatly increase the succes
study.
• The pilot study is indeed a prerequisite for the successful execution and completion of a research project and
expand knowledge about interventions and their effects on clients.
- Its function is the exact formulation of the research problem, and a tentative planning of the modus operan
of the investigation.
➢2. Sampling Techniques in Quantitative Research:
• The notion behind sampling theory is that a relatively small set of observations can give an idea of what ca
expected in the total population of the intended study.
• Both quantitative and qualitative researchers employ sampling techniques and there are many similarities
to sampling between the two paradigms.
• Certain practical issues include the concept of universe and population, reasons for using sampling, the siz
representativeness of samples and the drawing of a random sample.
, ➢ 2.1. Universe and Population:
• The term sample always implies the simultaneous existence of a population or universe of which the sample
section, or a set of individuals selected from the population.
• A distinction can be made between universe and population.
- The universe refers to individuals who possess specific characteristics.
• For example:
• All social workers registered by the South African council for social services professions (SACSSP) constitute a
When undertaking a study of child abuse, the population might include all social workers working in child pr
services.
• The population is the totality of persons, events, organizational units, case records or other sampling units w
research problem is concerned.
• Cozby defines the population as being composed of all the individuals you are interested in for your study.
➢ 2.2. Defining a Sample:
• Sampling in the quantitative paradigm means taking a portion or a smaller number of units of a population
representative or having particular characteristics of that total population.
- Leedy & Ormrod Add that the characteristics of the total population, in the same proportion and relation
the total population, should be seen in the sample.
• Royse, Thyer & Padgett state that 10% of the population makes an adequate sample, implying that the sam
considered to be representative.
