Introduction In quantitative research, much attention should be paid to addressing ethical and legal norms and rules. According to Wiles and Boddy (2013), research ethics can “encourage researchers not only to improve levels of ‘ethical literacy’ in the research community but more fundamentally, to reflect deeply on their research project and process from the perspective of all the possible stakeholders” (p. 1). As a result, the rights and interests of all individuals involved in the study can be discussed as protected if ethical and legal norms are followed. The purpose of this paper is to present the quantitative research question and discuss ethical and legal issues related to quantitative methodology. Overview of the Quantitative Question The following research question was developed for the quantitative study: Is there a relationship between the amount of time which students from grades 6-7 spend playing computer and video games and their achievement at school? The independent variable in this study is the amount of time that students can spend while playing computer and video games. The time is measured in minutes per week. The dependent variable is the students’ achievement that should be measured in weekly tests’ scores (from 0 to 100). Tests should cover the materials related to Language, Mathematics, and Science. The proposed research question is appropriate to be used in the study the aim of which is to find out how the students’ interest in playing computer and video games can predict their achievement at school. The IRB Process The Institutional Review Board (IRB) is a committee that is responsible for controlling the research process in educational and other types of organizations. The IRB process means filling in the specific form and receiving the approval to conduct the planned study (Metro, 2014). The IRB form includes the following information to mention: a purpose of the research, dates, a description of the process and procedures, a note regarding the voluntary participation in a study, principles of selecting participants for a study, a note on ethical issues and confidentiality, and a description of the withdrawal procedure (Metro, 2014). This information should be provided to the Institutional Review Board to guarantee that human participants’ rights and interests will be protected and non-violated concerning the proposed study. Ethical Considerations The involvement of children in a quantitative study is associated with a range of ethical issues. Therefore, researchers can start conducting a study only when informed consent forms are signed, and the permissions of parents are received (Tangen, 2014). For this study, the permission of parents and their involvement in the research process are critical because they help report the actual time spent on playing video and computer games (Wouters, Van Nimwegen, Van Oostendorp, & Van Der Spek, 2013; Yang, 2012). Thus, it is expected that the participation of students and their families is voluntary even though a random sampling technique can be used to determine the sample for the study (Smith, 2016). Also, it is important to guarantee that the test results of students and the private data are not shared publicly. Much attention shoul
