Population, Target Population and Sample: Why is it so confusing?

Target Population
Sample
Participants or data providing input or information about the sample
Population
The number of people or programs being studied or observed – e.g. Sample size=6
Data Collection/Analysis
This topic tends to be very confusing for the participants. Please take time to explain the slide. Remind them that the sample for quantitative studies needs to be much larger than qualitative studies. Learners will need to do a Power Analysis to determine how large the sample must be for a Quantitative study. For qualitative studies they are smaller especially if doing in-depth interviews– but may be much larger if using questionnaires with open questions since interviews collect a lot more information for each person in much more detail. Therefore interviews yield a lot more data per interview to do coding and thematic analysis.
3
Population And Sample
Identify the population of the study
Identify the sampling design (single stage or clustering)
Describe the selection process and procedure
Determine the sampling size
Sampling Methods
Random Sampling
True Experimental Procedure
Subjects Have Equal Probability of Being Selected
Sample Is Representative of Population
Nonrandom Sampling
Quasi-experimental procedure
Conveniently Selected
Usage of Naturally Formed Groups
Helpful Note: Examples of a Naturally Formed Group include school district, school, classroom, or specific organization
5
Random Sampling Methods
Stratified Random Sampling
Systematic Random Sampling
Cluster (Area) Random Sampling
Multi-Stage Sampling
Please share the following and your experience with students:
Stratified Random Sampling
Selection From Subgroups
Systematic Random Sampling
Selection From An Ordered Sampling Frame
Cluster (Area) Random Sampling
Selection From A Natural Homogeneous Groupings
Multi-Stage Sampling
Selection from pre-structured groups
6
NonRandom Sampling Methods
Convenience Sampling
Sample is conveniently accessible to a researcher
Sample is easy to access
Sample is not an accurate representation of the population
Purposeful Sampling
Selection of a specific group of people within a population
The selected group contains individuals that are most information
The intent is to describe the population as a whole
Examples of Purposeful Sampling
Modal Instance Sampling
Expert Sampling
Quota Sampling
Nonproportional Quota Sampling
Heterogenity Sampling
Snowball Sampling
7
Sampling Terminology
Population
Sample
Theoretical Population
Accessible Population
Sampling Frame
Population And Sample Commonly Held Questions
What is the primary difference between a population and sample?
Who do you want to generalize to?
Should the entire population be used as the sample?
How should the size of the sample be determined?
Professors please provide answers to these questions for students
