Question

You hypothesize that students in fraternities/sororities on your campus are more extroverted (on an introversion/extroversion scale) than other students. To answer your research question, you need to obtain a sample of “Greek” students and a sample of “independent” students. For each of these two populations of students, how would you obtain simple random samples using the four steps described in this chapter? (The four steps 1. Defining the population, 2. Constructing a list, 3. Drawing the sampling, 4. Contacting members of the sample) Chapter 7. Sampling Techniques

Answer 1

Introduction- Sampling is a primary task for any research, it is a process used in statistical analysis in which pre-determined observations are taken from a bigger population. The process and methodology used in sampling strictly depend on the type of research and methods of interpretation.

Steps of the Sampling-

1- Defining Population: Defining the population of interest is the first step in the sampling process, the target population is defined in the terms of the element, units, extent and time frames. The definition of the sample should be according to the research design and other related elements.

2- Constructing a list: The construction of list depends on the size of the samples and elements identified during sampling, a list should be easy to interpret on scales, a true representation of data and flexible for after changes.

3- Drawing the Sampling: One the definition of the population is clear, the researcher find out the common and odd elements from which the sample may be drawn. Drawing the sampling uses multiple signs, notions, and symbols to show data in a specific manner.

4- Contacting Members of the Sample: This step used to identify and recognize the data used as the sample, an identified data increase the value of research so researchers prepare a list of volunteers who provided samples. Contacting members list helps us to define the validity and reliability of the samples as well as research.
