Understanding Business Research Terms and Concepts: Part 2
Businesses will always need market research and it generally falls into two different groups. Qualitative and Quantitative. Qualitative research is “Qualitative research is designed to reveal a target audience’s range of behavior and the perceptions that drive it with reference to specific topics or issues. The results of qualitative research are descriptive rather than predictive.” ("What Is Qualitative Research?” 2015). Quantitative research “is about asking people for their opinions in a structured way so that you can produce hard facts and statistics to guide you. To get reliable statistical results, it’s important to survey people in fairly large numbers and to make sure they are a representative sample of your target market.” ("What Is Quantitative Research?” 2015). There also are descriptive and statistical approach’s in this paper that will help with understand what is best for you business research. When constructing a business research there are several sampling methods that can be used. Some sampling methods would be simple random sampling, systematic sampling, cluster sampling and quota sampling and etc. The article I chose to do is called Qualitative and quantitative methods for sampling zooplankton in shallow coastal estuaries. “Many different devices are used for sampling zooplankton. Every sampler has its advantages and limitations in terms of sampling ease and efficiency, which is why hydro biologists search for devices that could increase sampling efficiency and decrease human effort (Nunez et al. 2008).” In this article they used the plankton net sampling method and it is used to sample the lake or pond.” These sampling methods all have their strengths and weakness and to choose a particular method will depend on the characteristics of the lake or pond, for instance the algae, depth and the density. The three sampling methods used to sample zooplankton are net, trap and tube. The net sampling has it limitations but it is commonly used and it proves quantitative data. By using the net approach it gives large volumes of the water that was collected quickly. The other sampling trap method is called the Schindler-Patalas trap. This consists of a clear plastic box that would be lowered to an appropriate depth and then closed. This method will trap zooplankton inside and this measures the actual volume of water that is sampled. The third method is the tube that is made out of PVC or Tygon. “A tube is lowered into the water column, and when the bottom reaches the desired depth (near the sediments), a line is pulled to close the bottom with a rubber stopper or other device. The tube is raised into the boat and the collected water poured through a net to collect the zooplankton. This device also provides a high degree of certainty about volume of water sampled, but it may not be an effective way to sample large animals that occur at a low density, or animals that can detect and escape from a narrow sampling device." ("Plankton Web", N.D). The two approaches in statistical are descriptive statistics and the second is the inferential statistics. Descriptive research is a tool used by researchers; it shows both quantitative and qualitative data. But descriptive research has their own advantages and disadvantages as well. When going with the descriptive research design it requires specific forms of data collecting. Examples of data collecting are case studies and surveys. These are some strength because it provides multifaceted approach for data collection. Descriptive research designs also has other ways of data collecting and sometimes case studies that have news reports and personal accounts can be used. One of the weaknesses would be confidentiality because often time’s people are not truthful and they feel like they have to tell the...
