sampling process in research (PowerPoint Presentation Sample)
This is a power point presentation on course work topic of undergraduate student. The presentation is about sampling process in research. The presentation consist of 16 slides. I used different sources read different papers to make this presentation and give references at the end of presentation. The presentation highlight the following points.
1) Definition of sampling process.
2) Sampling process with all steps.
3) Factor influencing sampling process.
4) Last slides contain references.
Identify the target population
Select a sampling frame
Specify sampling technique
Execute the sampling frame
Determine the sample size
Execute the sampling plan
Factors influencing sampling process
Is the process of selecting a number of individual for a study in such a way that the individual represent the larger group from which they were selected.
OR a process whereby a researcher chooses her sample.
The representative selected for a study whose characteristics exemplify the larger group from which they were selected. Sample of study is simply the participant in a study.
The larger group from which individuals are selected to participate in a study.
It is the procedure or steps of selecting final sample unit. These steps are in sequential order
Sampling process refer to the selection of samples from a population. When the population of study is very wide then a sample is selected from the population which best represent the population.
IDENTIFY THE TARGET POPULATION:
The target population is the group of individuals, from which the sample might be taken.
Target population refers to the group of individuals to which researchers are interested in generalizing their findings.
For example: researcher wants to study the behavior of toddlers in playgroup. He has to select a particular area (e.g., all playgroups in his city) for his study because it is impossible to study the whole world toddlers
SELECT A SAMPLING FRAME:
Sampling frame is the group of individuals or objects (e.g., list of all playgroups in researcher’s city) from which researcher will draw his/her sample.
It is the list of all units in a study population from which the sample is taken.
For example: researcher takes 3 playgroups near to his house in his sampling frame to conduct his study.
SPECIFY THE SAMPLING TECHNIQUE:
Sampling can be done through probability (random selection) or non-probability (non-random) technique.
if the sampling frame is approximately the same as the target population, random selection may be used to select sample.
if the sampling frame does not really represent the target population, the researcher may choose non-random selection which can give at least an idea about the population in his nearby area.
DETERMINE THE SAMPLE SIZE:
The sample size is simply the number of units in the sample.
Sample size determination depends on many factors such as time, cost, and facility.
In general, larger samples are better, but they also require more resources
EXECUTE THE SAMPLING PLAN:
Once population, sampling frame, sampling technique and sample size are identified, researcher can use all that information to choose his/her sample.
