Determine the sample size: Fajar should determine the sample size he needs to achieve his research objective. A larger sample size will provide more accurate results.
Develop a questionnaire: Fajar should develop a questionnaire that includes open-ended and closed-ended questions. The questionnaire should be designed to collect data on the independent and dependent variables.
Conduct a pilot study: Fajar should conduct a pilot study to test the questionnaire's effectiveness, identify any issues, and refine the questionnaire accordingly.
Collect data: Fajar should distribute the questionnaire to the sample population and collect the responses.
Analyze the data: Fajar should analyze the data collected to determine the relationship between the independent and dependent variables.
Independent variable: The independent variable in this study is the beliefs of children towards environmental conservation.
Dependent variable: The dependent variable in this study is the response of children towards the questionnaire, which will reveal their beliefs about environmental conservation.
In summary, Fajar could conduct a study using a questionnaire to find out about the children's beliefs by defining the research question, population, and sample size, developing a questionnaire, conducting a pilot study, collecting data, and analyzing the data. The independent variable in this study is the beliefs of children towards environmental conservation, and the dependent variable is the response of children towards the questionnaire, which will reveal their beliefs about environmental conservation.
