Well in that case, you can apply descriptive statistics for exploratory insights. Moreover, for checking mean differences across variables through demographic properties of the respondents, you can use t-test or ANOVA.
I encourage my students to write your research questions in a simple regression equation. This means, students must define dependent variable, independent variables, and other demographic variables. This step can be done as students do their own literature review on the topic of interest (e.g., knowledge level of certain target population). After this step, students will obtain data sets. It is discouraged to collect your own data unless your thesis committee have agreed to guide you. Once data set is obtained, you would use some sort of statistical packages to test your hypothesis. There are many statistical packages you can use - some are free and some are not. Some universities have system-wide license for staffs and students, so ask your school's librarian. You may need to do further data manipulations prior to running any kind of analysis. This includes, cleaning, transforming, and imputing data. After you run your analysis, you would make interpretation. If you are not comfortable with making interpretation, I suggest you would arrange a meeting with faculty members of your institution who can give you further guidance. Good luck.
