Sampling Theory Part 1 Flashcards
It is the creation of sample set.
Sampling Theory
It retains the accuracy in bringing out the correct statistical information.
Sampling Theory
The entire group you want to draw conclusions about.
Population
It is the specific group where you will collect data from .
Sample
What do you call the sample in a research?
respondents
It is the process of selecting a small number of elements (sample) from a larger defined target group of elements (population) such that the information gathered from the small group will allow judgements to be made about the larger groups.
Sampling
What are the basics of sampling theory?
- Population
- Element
- Defined Target Population
- Sampling Unit
- Sampling Frame
This is any type of bias that is attributable to mistakes in either drawing a sample or determining the sample size.
Sampling Error
Explain the ways in developing a sampling plan.
- Define the Population of Interest
- Identify a Sampling Frame (if possible)
- Select a Sampling Method
- Determine Sample Size
- Execute the Sampling Plan
Population of interest is entirely dependent on:
- Management Problem
- Research Problems
- Research Design
Bases for Defining Population
- Geographic Area
- Demographics
- Usage/Lifestyle
- Awareness
It is a list of population elements (people, companies, houses, cities, etc.) from which units to be sampled can be selected.
Sampling Frame
A good sample frame for a project on living conditions would:
- Include all individuals in the target populations
- Exclude all individuals not in the target population
Factors to be considered in sampling frame.
- Unique identifier for each member
- Logical organization to the list
- Up to date information
