In this example, the researcher's claim would be something like:
"I believe that DVC students spend less than 1.5 hours on social media each day."
When conducting research, you need to be clear on what your claim is going to be. A claim is a statement that summarizes your opinion. It also provides the main idea that the rest of your essay should try to address. If your research is pursued with rigour and perseverance, you would most likely be able to prove your claim in the end.
