After the researcher has collected the data, the next step in the research process is the execution of the project (i.e., implementation phase of the project). This step is very important in the research process as it ensures that the research is being executed systematically and in time. If the execution of the research proceeds on correct lines, then the collected data would be adequate and dependable. If structured questionnaires are to be used for the survey, then data, i.e., both questions and the possible answers, may be machine-coded for easy and convenient usage. If interviewers are to collect data, then they should be accordingly selected, and proper training should be given to them. The researcher should ensure that the survey is under statistical control, i.e., the collected information is in agreement with the pre-defined standard of accuracy.
