Studies involving humans are for the most part badly designed. A few quality studies have been carried out over the years, starting in 1998 with a double-blind, placebo-controlled trial of 135 adults over 12 weeks published in The Journal of the American Medical Association. They found no evidence that hydroxycitric acid, the active ingredient in weight loss products made from garcinia cambogia, produced significant weight loss. The American Journal of Clinical Nutrition in 2004 published a systematic review of meta-analyses and clinical trials on dietary supplements for weight loss by complementary medicine researchers at the Universities of Exeter and Plymouth.
This is particularly true with regard to quantitative research techniques for two reasons: first, scientific and lay cultures are quite enamored by quantitative research techniques and tend not to look deeply at the design and mechanics of such procedures, and secondly, it is inordinately easy to design a quantitative research effort badly.
Benefits Of Quantitative Research. March 2, , Harri Daniel, Comments Off on Benefits Of Quantitative Research. Benefits of Quantitative Research. Quantitative research uses traditional statistical and mathematical methods for measuring results conclusively. All quantitative experiments use a single standard format.
Quantitative Advantages. You may be very familiar with quantitative research from your science classes where you learned and practiced using the scientific method. 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.
using standards means that the research can be replicated, and then analysed and compared with similar studies. Kruger () confirms that 'quantitative methods allow us to summarize vast sources of information and facilitate comparisons across categories and over time'. Benefits of Quantitative Research In addition to providing researchers with a fast and efficient way of studying a large sample size, quantitative research yields objective results. Researchers gather objective, numerical data through quantitative research that is difficult to interpret in multiple ways.
