Mixed method questions blend quantitative and qualitative research questions ends. Thus, within the same mixed-method research question combine qualitative and quantitative study ends. In bringing out the strengths of either qualitative and quantities research questions for this study, preference is made both qualitative and quantitative research questions are stated together but classified and the mixed method questions left out.
The criteria of the questions are as follows: First, pose the quantitative questions starting with the descriptive questions, how do transportation operators in fifty states in the United States of America (USA) perceive the mainstreaming of the ISO 14000 certification benchmarks? How do transportation operators in fifty states in the United States of America (USA) perceive environmental care? What are the aggregate numbers of transport operators in the United States of America (USA) that are achieving environmental care through mainstreaming the ISO 14000 certification benchmarks? What are the aggregate numbers of transport operators in the United States of America (USA) that are achieving environmental care through mainstreaming the ISO 14000 certification benchmarks? What are the aggregate numbers of other energy-consuming industrial players that are mainstreaming the ISO 14000 certification benchmarks?
These are then followed by inferential questions: Do mainstream the ISO 14000 certification benchmarks relate to environmental care by the transport operators? Secondly, state the qualitative research questions starting by posing the central question, “What interactive experiences are shared by transportation and logistics management in mainstreaming global environment concerns?”
Sub-questions associated with this will explore and narrow into why transportation operations and logistics management have coexisted? What does environmentally friendly transportation mean? Moreover, what has been the experience like in applying logistics solutions in spite of environmental concerns?
