研究方法论被认为是系统地解决研究问题的一种方法。换句话说，它可以被认为是一门研究科学研究方法的科学(Dane, 2011)。研究人员在进行研究时必须能够选择合适的研究工具和技术。这将有助于他们有效地制定研究方法。文章代写assignment-数据收集方法和样本，探索相应的研究方法和数据收集技术(Knoll & Schramm, 2015)。
The sample size of the research is 118 students who were to establish an association with four Facebook profiles. Two professors were also engaged in the experiment, among which one professor is known to all the participants while the others are unknown (Ozturk, 2016). The researchers in the research had collected primary data through the online questionnaire survey. The students were asked to visit four Facebook profiles and were requested to examine the profile thoroughly. The students clicked on the link to be redirected to one of the four Facebook profiles randomly and after which they were directed to start the questionnaire survey by clicking on another link. However, after the completion of the experiment, the detailed information about the research was emailed to each student. It was found out that 26 participants were excluded from the experiment as they already had detailed knowledge about the products and so they had fixed attitude (positive) and behaviour in comparison to the other students. Hence the actual sample size was reduced to 92 to avoid experimental manipulation (van Velzen, 2016).
Types of Data Collected
The researchers in the research have collected only primary data from 118 students through the research instrument of an online questionnaire. These primary data were appropriate for the purpose of the research. This is because, in order to investigate the impact of the user-generated content on online advertising, the users who are actively engaged in the social media activities should have been researched (Ganesan & Kirana Kumar, 2015). The researcher has rightfully selected young students for the research and directed them to participate in the online questionnaire survey to collect the primary data from them. The primary data was collected as it helped the researcher to address the specific research issues on the role of collective influence and personal influence on the online advertising. Through the primary data collection, the researcher was able to exercise greater control of the social media market and retrieve higher level of updated information (Alsayed, Maguire-Wright & Flickinger, 2016). However, the researcher could have collected a secondary data to underpin the research outcome substantially. The researcher could have collected information and data from the second sources of information such as journal articles, peer-reviewed articles, books, and magazines. The secondary data could have ensured feasibility of both the international comparative studies and longitudinal studies for fulfilling the research purpose. With the help of the secondary data collection, the researcher could have been able to carry out the study on a worldwide basis with the same criteria of the research undertaken (Hughes, 2012). For example, the data collected from the World Values Survey on the response and participation rate of the users on the social media websites could have reinforced the research purpose of the current research to examine the user generated content and the online advertising. Thus, apart from the primary data, the researchers could have also collected the secondary data to strengthen and further support the research purpose (Stein, 2015).
