Answer A

The research questions are as follows:-

  • What is the different type of methane emissions that each country across the world faces?
  • What are the key reasons behind such emission?

Answer B

The selected data sample is of 1517, where different countries across the world have been selected based on the emissions throughout the years.

Answer C

The key variables of the research are emission, country name, type of emission and reason for such emission.

The classification of the given data is as follows:-

  • Country Name-Nominal Variable
  • Reason-Nominal Variable
  • Emission-Ordinal Variable
  • Type of Emission- Discrete Variable

Answer D

The main issue is to classify the dependent and independent variables. The sample size is huge; therefore, data clustering is also an issue for the given data set. In addition to this, it can be also said that proper year and time is also not properly mentioned in the given data set.

Answer E

The selected numerical variable is total number of emissions.

Figure 1: Number of Emissions

A wide variety of sources, both natural and anthropogenic in origin, are known to be contributors of methane emissions. Agricultural practises, coal mining, industrial processes, landfills, mobile and stationary combustion, natural gas and oil systems, and wastewater treatment are all examples of the wide variety of activities that fall under the category of anthropogenic sources of emissions. Methane emissions are the primary contributor to the formation of ground-level ozone, which is both a harmful air pollutant and a greenhouse gas. Methane is a hydrocarbon that can be found in natural gas. The presence of this chemical is linked to the early death of approximately one million people per year. As a contributor to global warming, methane is among the most powerful greenhouse gases. It has a warming potential that is 80 times higher than that of carbon dioxide when measured over a period of twenty years.

Answer F

The selected variable is reasons for emissions. The overall data is as follows:-

Figure 2: Various Reasons for emissions

As a greenhouse gas, methane is much more powerful than carbon dioxide when it comes to warming the atmosphere. One metric tonne of methane is 28 times more likely to warm the climate than one metric tonne of carbon dioxide over a hundred years, if there are no climate feedback processes.
