First, read the English article below.

Some topics and projects will call for primary research, which means that you'll collect the data yourself. If you've got a really localized topic--like the obesity problem at your University, for instance--you might want to consider creating a short questionnaire or other way of analyzing data of concern to your project. No surveys or questionnaires get to everyone. How many would be enough to get a good sense of the issue. Will it mean anything to gather opinions about obesity form 20 guys in the locker room? Everyone on your dorm floor? 300 people at the football game? Be conscious of bias. Aim for a somewhat distributed mix of men and women, of different ages, socioeconomic backgrounds, and places of birth. If you're after opinions, a questionnaire is the best and most efficient way of collecting data, but it might not be particularly applicable to your topic.  If you're interested in food habits and the availability of junk food in cafeterias, consider posting up beside the lunch line a few days a week and counting the number of students who forego the full lunches in favor of deserts, sodas, or candy. Keep a running tally. Interviews might be good if you have access to experts or other parties involved directly in the topic you're researching. If you want to learn about school lunches, talk to the lunch workers, the principal of your school, or other people who may be involved. Let them know what you're researching and explain the project before talking to them. Once you've picked a method of collection, distribute your surveys, observe your behaviors, or conduct your interviews and collect your research. Analyze the research and summarize your findings in a way that you'll be able to use it for your research. If your hypothesis about the research ends up being wrong, don't fret. This in and of itself can be a good source of information to present in a project, displaying your commitment to finding out "the truth" of the topic at hand.
