Topic 3 DQ 2: Expert Answer and Explanation
There are many approaches researchers can use to evaluate evidence. However, researchers should select the best methods that can work for them. That said, the key approaches that will be used to analyze evidence in this project are interviews and surveys. According to J. Phillips and P. Phillips (2016), survey is an evidence evaluation method where one is allowed to use series of questionnaires to gather information about the evidence. Through surveys, researchers are at liberty to use the open-ended or free-response inquiries to gather data.
Apart from questionnaires, researchers can also use checklists as instruments to collect information about the evidence being evaluated. Järvelin and Kekäläinen (2017) define interview as the approach that can allow the evaluator to structure questions in a way that provides the interviewees the environment to respond to the questions freely. Interviews require that the structured or semi-structured questions are responded to in a documented form.
The following are the differences between the approaches. Järvelin and Kekäläinen (2017) report that through survey, researchers can cover many topics at a time while interviews can hinder the scholar from collecting much data because it takes a lot of time. Another significant difference is that surveys are conducted through instruments, such as checklists and questionnaires.
However, interviews require that the researcher meets the participants fac-to-face. Though the two approaches are different, they are similar in the following ways. First, they can be used to evaluate the objectives, goals, and the findings of evidences. Second, the two methods can provide the researchers with opportunity to create a relationship with their respondents. Lastly, data collected using the two methods are easy to analyze.
