In order to answer these questions you will want to research each of the questions. You will need to figure out the best and most reliable way to answer each question (and the questions will probably each need a different research strategy).
this shows that research isn`t just one way, its different questions for every part.
To solve problems, researchers may employ a range of methods. Each discipline has its own methods for making or vetting knowledge claims. In Psychology, for example, experimentation with human subjects is quite common, but it is less common in Mathematics. Part of becoming a skilled researcher is learning the epistemology of one’s discipline.
every field has its own way if doing research. its important to understand the methods used in your discipline.
