Briefly explain what methodology is.

Methodology is an analysis of the methods used to make inquiries or to do research in a particular field of study.
In the field of history, for instance, historiography is the study of methods used to analyze and interpret historical events. Historiography applies the method of analyzing multiple sources—written documents, but also music, art, and objects of everyday use.
There are some methods of historiography that have chosen to examine history through the experiences of a particular group. For example, there are some historians and scholars in American Studies who examine history through the experiences of Black Americans or women.
In the field of British history, E.P. Thompson wrote a well-known book, The Making of the English Working Class, in which he considered them as agents of history, with more influence on British culture than many people had previously realized, especially given that most methodologies had focused on the middle-class.
