A systematic investigation and evaluation of all information on a particular topic is called:

The term that best describes a systematic investigation and evaluation of all information on a particular topic is a literature review. This process involves a comprehensive search of existing research, theories, and findings related to a specific subject area. It aims to summarize, synthesize, and critically assess the available information to identify gaps in knowledge, inform future research directions, and provide context for new studies or theoretical frameworks.

A literature review serves multiple purposes, such as helping researchers understand the current state of knowledge, refining research questions, and justifying the significance of new research efforts. It is typically structured and follows defined methodologies, which differentiate it from other options listed.

In contrast, a research hypothesis refers to a specific, testable prediction about the relationship between variables, rather than an evaluation of existing information. An analytic study focuses on examining data to uncover relationships or trends but may not encompass the breadth of evaluating all existing literature on a topic. Qualitative analysis involves examining non-numerical data to understand underlying meanings and experiences, but again, this is not synonymous with systematically reviewing literature as a whole.
