Design (Qualitative, Quantitative, and mixed methods approaches) - Research Paper Example The use of sub-questions would be useful exploring the answers to the research question. Qualitatively written questions help in gaining an understanding of essential reasons, motivations, and opinions. It offers perceptions into the problem or rather helps in developing ideas or assumptions for prospective quantitative research. In addition, qualitative research is used to expose trends in opinions, and expound further into the problem (Petty, Thomson, & Stew, 2012). The techniques for data collection in qualitative research methodology include individual interviews, focus group, and observation. All of these will be useful in researching Green Logistics Chain and Issues because the sample size remains typically small also requires an exploratory research approach. The two forms of writing quantitative research questions include descriptive research questions and comparative research questions. Descriptive research questions aim at describing the variables being measured (Petty, Thomson, & Stew, 2012). The word describe implies that the research questions seek to quantify variables one intends to measure. For instance, the question that begins like, how much, how often, and what percentage are usually used in describing quantifiable variables. Descriptive research questions concentrate on just one variable and a group though they can comprise multiple variables or even groups. Comparative research questions seek to examine the variances between two groups on single dependent variables. Such questions typically begin by asking "what is the variation in" (Amelina, 2012). Descriptive research questions are essential for the quantitative research in answering this topic. For instance, how much CO2 results from Freight transport emissions. The desc riptive research question will attempt to find out the quantity or amount of CO2. Mixed methods research questions apply various
