Whilst completing this assessment task, you will identify appropriate methods of data collection relevant to yourtopic. You will subsequently perform the data collection and apply both qualitative and quantitative statistic alanalyses to draw insightful conclusions from the data. As part of this work, you are required to also identify potential sources of error in the collected data, e.g. instrumentation errors. You will also demonstrate the use and interpretation of one- and two-dimensional statistical analysis techniques through the analysis of the collected research related datasets. Part of your work will need to include a statistical validation check and you will need to comment on the reliability and limitations using established engineering techniques. Finally, you are to also propose solutions to add to or improve the quality of the data. Identify the sort or type of data that you will would collect and how you would go about obtaining it.

Statistics is used, here, to find a pattern within the data. Present your data and findings in the most meaningful way so that it is interesting to a professional audience.

Data Collection

The research paper is prepared in order to understand the pertinent problem regarding rise in global warming and changes in the climate all over the world due to rise in the emission of greenhouse gases globally. The rise in the temperature has led to problems in the living style of the individuals. There have been various types of processes that have been undertaken in order to reduce the level of temperature and it is seen that even the society has undertaken various strategies to make use of the heat for sustainable purposes and even reduce the temperature in the given locality. The use of heat absorbing materials is a new initiative with the help of which the electricity can be generated and the heat can be absorbed to reduce the air temperature of the area.

The use of solar panels is an advantageous method with the help of which the the heat energy from the sun is converted into electrical energy that can be used for various purposes in order raise the standard of living and even reduce the temperature and thereby reducing the adverse impact on the environment. However, it is seen that there are various other alternate methods that can be used to reduce the heat of the atmosphere. This has created a confusion among the consumers as they are not sure which process to use and which is the process that will be more advantageous to them. This pertinent problem has motivated various researcher to undertake researches that will be influential to find out the correct answer.  The paper primarily has the idea of collecting data with respect to the topic and then undertake extensive analysis in order to gain the accurate results.

It is seen that in this study, the researcher has made use of primary data as the data from the direct sources will be influential for the giving out the best results. The paper utilises quantitative and qualitative statistical tools in order to analyse the data that are obtained so that precise and accurate results can be obtained for understanding whether the solar panels are influential as a heat absorbing material in buildings. The data has been collected with the help of the questionnaires and the questions have been constructed with respect to the pertinent problem.

The researcher has preferred a particular region where the rise in temperature has been increasing a vast rate during the current years. The people in this area have sufficient knowledge about research problem and therefore, the data that have been collected can be useful for the gaining accurate results. The time frame of the research being limited has compelled the researcher to select a sample size of thirty respondents that will be chosen from the preferred geographical location of the researcher. The sample has been chosen with the help of the probability simple random sampling that will aid the researcher to cover the entire population of the selected region and therefore, a representative from the various regions of the area can be chosen who can give out their feedback regarding the same research problem. The use of this sampling method can be useful as it gives the opportunity to the overall population a chance of getting selected as a respondent.

Sample Selection and Size

The questionnaire that has been framed comprises of close ended questions that are topic specific so that it will be easier for the participants to answer without any difficulty.

The evaluation of the research topic show that there are several areas where improvements can be undertaken in order to enhance the research process. A suggestion can be given that undertaking a larger sample size will be helpful for giving out better results as a larger sample size will include more participants from the population and thus various new answers and ideas can be obtained that can be essential for accurate and precise results. It is even seen that if the research is undertaken within a larger time frame, then the researcher will get sufficient time to undertake the research and thus better analysis is possible that will give out appropriate results.

Conclusion

The evaluation of the research paper reveals that quantitative and qualitative analysis is undertaken in the research so that the data can be scrutinised effectively and the research problem can be identified and rectified with ease. The use of descriptive statistics and correlation is useful for the research and evaluation of the primary data reveals that solar panels are the most cost-effective measure that is useful for reducing the temperature in buildings and the use of solar panels even aids in the generation of electricity through renewable sources that will decrease the pressure over the non-renewable sources thereby helping the environment to stay fit and healthy.
