Types of Sampling
This is the simplest way to ensure that every member of a population has an equal chance of being selected. You can use a random number generator, draw names from a hat, or use any other method that's random.
Simple Random Sampling
This is accessing information that has already been researched and can be found in books, other publications and expert sources.
Secondary Research
This typically consists of a researcher having a discussion with a participant based on questions developed by the researcher
Interview
This is a simple random sampling technique that allows you to select the desired number of units from a population with a single random start.
Systematic Sampling
_______________is that which is original. It is research that the researcher designs and carries out using surveys and/or focus groups.
Primary Research
A researcher using this method gathers a group of people with intimate knowledge of a communication phenomenon. __________also tend to produce useful information at a higher rate than interviews.
Focus Groups
This method involves dividing the population into subpopulations that may differ in important ways. It's a non-probability sampling method, meaning it's based on the relative size of each subgroup, not on random selection.
Stratified Sampling
The two types of primary research
Quantitative and Qualitative
As the name indicates, this method involves the researcher watching participants in their natural environment. In some cases, the participants may not know they are being studied, as the researcher fully immerses his or herself as a member of the environment.
Participant Observation
This method is useful for large and diverse populations. You divide the population into subgroups with similar characteristics, then randomly select an entire subgroup.
Cluster Sampling
This type of research is widely used. It is based on information findings taken from observation, interviewing and from tracing patterns of behaviour.
Qualitative Research
This is a form of textual analysis wherein the researcher systematically analyzes, interprets, and critiques the persuasive power of messages within a text.
Rhetorical Research
This is the easiest form of sampling, as it involves selecting people who volunteer to be questioned. It can be helpful for businesses with small budgets to quickly gather relevant information.
Convenience Sampling
This type of research is widely used. It is based on information findings taken from observation, interviewing and from tracing patterns of behaviour.
Qualitative Research
This approach results in a research study that uses two or more methods spoken about in the presentation
Mixed Methodology
