Discovering the truth in various fields requires research to be done with respect to the field under study. One has to define the objective of the research clearly as this provides the scope and focus of the research and determines the research methods to be used. The Article title is misleading as it does not clearly state to the reader what exactly it is about. The article discusses the issue of health while at the same time contains detailed information on the manufacture of solar cells. Thus, the reader cannot clearly identify the objective of the article Failure to define clearly one’s objectives in the research may raise doubt as to whether one has sufficient understanding of the problem. There is a clear outlining of the source of information used in the article. This is a good research practice as one can easily validate the information contained in the article by referring to the sources. Unless secrecy is necessary, the research should reveal how the information used was obtained and also state its source. This gives the reader confidence as it is easier to determine the validity and reliability of the data supplied. The objectives put in place during a research, determines whether the research will be as success or a failure.

Use of different approaches to research with different study designs help to meet the objectives of the research. Factors and relationships identified in a sample through quantitive research should be assumed true of the whole population from which one obtained the sample. This research design is an excellent way of results finalizing and prove of hypothesis. The method is expensive and requires a lot of time. Another study design known as qualitative research design is a naturalistic interpretive approach that seeks and explains reasons people act and make decisions. Research methods should ensure the answers retrieved are valid and reliable regardless of the study design employed.
Conrolled observation, documented studies and interviews, form one of the best approaches to maximize results in doing research. More often than not, research reveals only an approximation of the truth due to various limitations arising while undertaking the process. Closeness of a piece of research work to the truth will depend on the quality it has. Since research efforts vary widely, there is considerable importance in how much confidence can be justifiably placed in a research. By including supporting references in the article, the writer gives one confidence in the information contained.
Irrespective of the research technique employed one has to pay special attention to the sample under study. The sample should provide a clear understanding of the applicability of one’s study to their situations and their understanding of the same population. It is thus important to select proper sampling method by which selection of individuals is random to provide insight into the entire population under study. Simple random and stratified sampling ensures that a sufficiently random sample of the general population becomes a representative of the whole. The writer’s concentration is only in the United States of America and a village in China. This sample size is small compared with the whole world population. Thus, conclusions on the health effect of solar cells manufacture are not justifiable.
Studying the wrong sample will give poor results of one’s research subjecting it to criticism. When conducting interviews, questions should be non-biased and easy to understand for the interviewees. The wording of the question should not lead the respondents as they may give biased responses. Chances of biased results increase with questions that are hard to understand. Data gathering, its analysis and appropriate conclusions are the main steps in any research work.
Use of reliable sources, performance of experiments, and through teesting of the hypothesis is very important. The writer’s sources like the Washington post and the environmental science and technology issue are reliable sources of information. Failure of the test results to support hypothesis does not mean failure of the research. On the contrary, these outcomes provide an opportunity to gain new knowledge by revisiting the hypothesis. With historical research techniques employed, data from the past should be reviewed, and conclusions verified to ascertain that it is factual. Flaws during research have effect on the validity and reliability of data. Therefore, a researcher should be sensitive to this so as to obtain a basis for determining their influence.
There is a temptation among researchers to increase basis of induction by including personal experiences not subject to controls under the gathered research data. This decreases objectivity of the research and weakens confidence in the findings. Drawing conclusions from the study of limited population and applying them to the larger group is undesirable too. Specifying the conditions under which the conclusions seems valid is something a good researcher has to consider. A good researcher will specify the conditions under which the conclusion seems valid failure to which confidence in the research weakens considerably. Including information about their qualifications, researchers allow the reader to judge them appropriately. The write of the article clearly indicates his experience and skills. Restrained language, clear and precise assertions, carefully drawn and hedged with appropriate reservation and apparent effort to achieve maximum objectivity, leave a favorable impression of the researcher. He dwells a lot on science behind the manufacture of solar cells instead of their health effects. On the other hand, generalizations that outrun evidence upon which they are based, exaggeration and unnecessary verbiage leave an unfavorable impression.
