What do you want to learn? Don't you have any goals? Just to finish the task assigned by the teacher? There are at least some directions (such as the relationship between breastfeeding and infant dental caries)

Secondly, determine the focus of the research topic:

In other words, you study and demonstrate (for example, breast-feeding can effectively reduce the incidence of dental caries than milk powder)

Determine the research object of the research topic:

Research group \ control group \ research scope, etc. (study group 10 infants \ control group 10 infants mainly fed with milk powder \ the research scope was 20 infants aged 3 months in a maternal and child health hospital from March to May 2008)

Determine the research method (standard version of infant dental caries diagnosis) (statistical analysis)

Data collection: You can go to the maternal and child health hospital to investigate in person, or you can get information from your tutor or other channels (grade 2 freshmen, it is recommended to go to the front line to make a deep impression on you and be good for your future study).

Collating data: It may be necessary to collect more data about children, because some confirmed subjects and data may be interrupted or lost in the next two months. This step is carried out simultaneously with data collection.

According to the selected research methods, statistical analysis was carried out.

Draw a conclusion (the relationship between P and 0.05)

Of course, I have to explain the whole process to my tutor and let him criticize and correct me.

Actually, you should give me 200 more points. Answering your 0-point question wasted my time answering several 200-point questions.

But it doesn't matter. These are the topics I did after I graduated from college. I hope it inspires you.
