Exam 8: Understanding Research Methods, Populations and Sampling

Participant observation is the same as observation, with one major difference, the researcher is a participant in the action s/he is observing.

Simple random sampling:

Data Collection methods, research populations and samples and sampling methods are fundamental elements of:

The researcher must know what kinds of data are needed and where the data are to be found, before decisions can be made about how to gather that data.

Visual methods involves the analysis of visual images. Any kind of visual images can be used, maps, charts, photographs, drawings, paintings, cartoons, videos and films and so on. The researcher can gather visual images or s/he can create visual images, or they can ask participants in the research to give visual images to the research project or to create visual images for the research project.

Simple random sampling, systematic sampling, stratified sampling and cluster sampling are all examples of :

Ethnography is a data gathering method.

Researchers are very pragmatic when it comes to research methods. They use whatever method of data collection is most appropriate, whatever data collection method will work best.

Data gathering methods are:

The basic rule of probability is that:

Projective techniques are a data gathering method.

National Lotteries use a:

Give three examples of research projects without human populations.

Researchers are very pragmatic when it comes to research methods, they use:

The data gathered must be:

Decisions with regard to whether to work with an entire population or a sample of the population are made based on the size of the population, the time available for the research, and the requirements of the research.

There are two kinds of sampling, probability and non probability sampling.

The key issue in sampling is that of representation. The concept of representation relates to the degree to which a sample drawn from a population can be said to be representative of the population.

The population of the study is:

The emphasis in non-probability sampling is on the capacity of a relatively small number of cases to clearly and comprehensively illustrate the phenomenon under investigation.
