Writing out an explicit thesis statement allows you to articulate your major points and to see how well they carry out your purpose and appeal to your audience. (Depending on the purpose, audience, and genre of your project, you may or may not decide to include the explicit thesis in your final draft.)
Although the thesis may confirm your research, you may also find that your hypothesis is invalid, inadequately supported, or insufficiently focused. In such cases, you need to rethink your original research question and perhaps do further research. To test your thesis, consider the following questions:
How can you state your thesis more precisely or more clearly? Should the wording be more specific? Could you use more specific, concrete nouns or stronger verbs? Should you add qualifying adjectives or adverbs?
In what ways will your thesis interest your audience? What can you do to increase that interest?
What evidence from your research supports each aspect of your thesis? What additional evidence do you need?
