What are the characteristics of quantitative research

Note that there are also reporting guidelines for different study designs: Exercises If the idea of a panel study piqued your interest, check out the Up series of documentary films.

However, it should be much more concise in an article, and furthermore, new literature might have been published during the time you were doing your study so include these here. Blinding of the experimenter is important to stop him or her treating subjects in one group differently from those in another.

Validity, trustworthiness and rigour: Perhaps we decide that to understand the transition to college, we need to know whether respondents ever cheated on an exam in high school or college. The time that survey researchers ask respondents to spend on questionnaires varies greatly.

The research study can usually be replicated or repeated, given its high reliability. As mentioned, the hope is that you will receive a good portion of the questionnaires you distributed back in a completed and readable format.

In this research method, you use your own experiences to address a cultural, political, or social issue. Weaknesses of survey research include inflexibility and issues with validity.

Focus groups provide a valuable means to pretest messages and materials, for audience members can provide spontaneous reactions and explain their responses.

Descriptive studies of a few cases are called case series. For example, for several years Gallup has polled Americans to find out what they think about gas prices something many of us happen to have opinions about.

However, it has been argued that measurement often plays a more important role in quantitative research. Ethnography is the study of people in their own environment through methods like participant observation and face-to-face interviewing. Earl Babbie Babbie, E.

Generally, quantitative methods are designed to provide summaries of data that support generalizations about the phenomenon under study. Discuss why pretesting is important. Ethical considerations or lack of cooperation compliance by the subjects sometimes prevent experiments from being performed.

This will give you a good idea about what sort of time estimate to provide respondents when it comes time to actually administer your survey, and about whether you have some wiggle room to add additional items or need to cut a few items.

Quantitative research focuses on numeric and unchanging data and detailed, convergent reasoning rather than divergent reasoning [i.

Research Methods: Qualitative Research and Quantitative Research

For a descriptive study with a wide focus a "fishing expedition"your main interest is estimating the effect of everything that is likely to affect the dependent variable, so you include as many independent variables as resources allow.

They are also referred to as interventions, because you do more than just observe the subjects. Products are presented for evaluation multiple times by the subjects. You can approach this crucial issue via statistical significance, confidence intervals, or "on the fly".

If you are doing a study on adherence to HIV treatment in South Africa, start with some information on the HIV epidemic, then the treatment options and lastly the issues with adherence. If the treatment effect is unlikely to wash out between measurements, a control group has to be used.

Another way to avoid problems of social desirability is to try to phrase difficult questions in the most benign way possible. If you used a adaptation of a standard tool, you can refer to an article in which it is described. As you might imagine, panel studies can be difficult and costly.

Start with an outline subheadings, paragraphs, key words on what is covered. The discussion should meld together your findings in relation to those identified in the literature review, and placed within the context of the theoretical framework underpinning the study.

The Cons of Quantitative Research. Here are the main disadvantages of quantitative research: • Needs a Huge Sample of Population: In using this type of research, you need to find great numbers of correspondents. The larger the sample of people, the more statistically accurate the outputs will be.

By Daniel Smith – January 20, () is one of the best sources for some best practices of quantitative studies, and he outlines some basic principles of a quantitative study on pages Challenge #1: Too broad of a topic.

Developed by Tragon Corporation inQuantitative Descriptive Analysis (QDA)® is a behavioral sensory evaluation approach that uses descriptive panels to measure a product’s sensory characteristics.
