Roger is interested in whether pet owners are more likely than those who do not own pets to have healthier lifestyles (e. G., exercise regularly, drink moderately, and refrain from nicotine use). By comparing the numbers he gathers on both groups, Roger will most likely be using what type of research?

By comparing the numbers he gathers on both groups, Roger will most likely be using quantitative research.

Explanation:

Roger will be comparing the numbers he gathers on both groups, and that is an example of quantitative research. This type of research works with numerical data (numbers). For that reason, it relies on mathematics, computations, and statistics to visualize the results. Its goal is to quantify something. On the other hand, qualitative research works with more abstract concepts.
