Differentiate descriptive, historical, correlational, and experimental research methods.
Provide clear definitions of each.
Use examples that point out the factors that make each unique. Provide detailed literature support for your answers. I am looking for at least of 2 pages of quality work with complete references. Thank you.© BrainMass Inc. brainmass.com October 25, 2018, 12:53 am ad1c9bdddf
I will explain each one at a a time, but I will start off with experimental research methods
This is when a researcher wants to scientifically study a phenomena. There are various steps in setting up an experiment; here are the key points:
- the researcher needs to identify a variable that they want to test.
- they need to randomly assign individuals to two groups: a control group which does not receive any treatment; an experimental group that receives the treatment (the variable that is being test).
- they set up hypothesis to test their theory
- the experimenter then will test both groups in a similar way
- after the test, the experimenter will examine the results of both groups to see if there is a significant difference between the groups. If there is, it might be attributed to the variable in question.
Some of the key elements of experimental is that the researcher is able to manipulate a variable, that they can randomly select individuals to be part of their research. As you will see, this differs from the other methodologies, as it makes it more scientific and statistically sound in ...
This posting looks at 4 research methodologies. It defines each one, and provides examples to illustrate each method. There are also links for further research and readings provided after every method.
Descriptive, Historical, Correlational, & Experimental Research
1. Education is often used as an indicator of a person's socioeconomic status. Historically, the number of years of schooling completed has been recorded in the Census of Population as a measure of education. Critics say that this measure is no longer accurate as a measure of education.
Comment and support your reasoning.
2. What problems might be involved in attempting to utilize attitude measures to predict specific behavior?
Support your answer.
3. A client tells a researcher that she wants a questionnaire that evaluates the importance of 30 product characteristics and to determine how her firms brand rates her brand and 10 competing brands rate on these characteristics. The researcher believes that this questionnaire will induce respondent fatigue because it is far too long.
Should the researcher do exactly what the client says or risk losing the business by suggesting a different approach?
Support your conclusion(s).
4. Differentiate descriptive, historical, correlational, and experimental research methods. Provide clear definitions of each. Use examples that point out the factors that make each unique. Provide support for your answers.View Full Posting Details
