One of the hardest parts of using research is how to weave it into your thoughts. You should not just stick a quote into a speech without adding some transition into it or without having it lead to the points you are making. Research can just look like an awkward afterthought if done wrong.
Poor example:
Everyone should consider riding a bicycle at least some of the time. Even using it instead of a car a few times a week would save a lot of money, especially now that gas is so expensive.
According to the website Flex Your Power at the Pump, “In the Netherlands and Denmark, bicycles are used for up to a third of all trips, and in German cities, bicycling increased by as much as 50% between 1972 and 1995.” So even adding a few trips on bikes every week instead of cars can save you money at the gas station.
While this statistic might be useful somewhere in your speech, it doesn’t relate to the point you were making about the costs of gas. It feels tacked on just so some research could be included.
