Quantitative Research is used to quantify attitudes, opinions, behaviours, and other defined variables – and generalise results from a larger sample population. This is generally done through online surveys, paper surveys, face-to-face interviews, telephone interviews, questionnaires and online polls.
Qualitative Research is used to gain an understanding of underlying reasons, opinions, and motivations in relation to lived experiences, emotions or behaviours. This is generally done in interviews, open-ended questions, or focus groups (group discussions) and observations.
Mixed Methods Research combines both Qualitative and Quantitative Research methodology.
Locating Quantitative & Qualitative Articles
The PsycINFO database allows limiting a search to studies that use a particular methodology. Look for the Methodology box. Qualitative and quantitative are both options there. You can also add the words "qualitative" or "quantitative" to the search. Eg. "substance addiction" AND qualitative and "substance addiction" AND quantitative
Having a particular research methodology in mind, include keywords to describe it in the search. Eg. "substance addiction" AND survey
Note: Mixed methods articles can appear when you search for "Quantitative Studies" and "Qualitative Studies."

SAGE Research Methods (SRM) is a research methods tool created to help with planning and conducting the research project. Researchers can explore methods and concepts to help them design research projects, understand particular methods or identify a new method, conduct their research, and write up their findings.
There are some useful research tools to guide in conducting research, including the following:
A visual representation of how methods, terms and concepts are related to each other.
Find books, book chapters, and journal articles on research methods and statistics. You can browse them by specific method or by discipline.
This tool guides you through your research project by going through each stage.
Helps you select the most appropriate statistical test.

The APA defines an empirical study as a "study based on facts, systematic observation, or experiment, rather than theory or general philosophical principle". Empirical studies articles are published in scholarly/ peer-reviewed journals.
Many databases allow you to limit your search to only empirical studies. In PsycINFO, look for the Methodology search option and use that menu to refine your search by limiting the articles to Empirical Studies only.
Another strategy for finding empirical studies is to add to your keywords some of the following search terms: empirical, research, observation, survey, experiment, findings, "action research", method*, longitudinal study, "participant group" or participants.
A literature review provides a comprehensive review of the literature in a specific area of interest. Preparation of a literature review may be divided into the following steps:
You might want to write down a description of the research question, area, or topic that you will be reviewing.
# The question frameworks can be helpful in this task.
Consult one or more databases to find information on your topic.
# The Effective Searching page provides further explanation.
# Check our guide here for detailed insight on finding the grey literature.
Focus on the Abstract, Introduction and Conclusion to establish usefulness and to get an overview of the main ideas, content and purpose. Summarise and make notes using the matrix.
Identify points on which the articles agree, disagree, or don’t cover at all.
Like any other academic text, your literature review should have an introduction, a main body, and a conclusion.

As you read and evaluate your literature there are several different methods to organise your research. You may consider using the matrix below for your note-taking and analysis:
When you create your own matrix, the first few columns should include (1) the authors, title, journal, (2) publication year, and (3) purpose of the paper. The remaining columns should identify important aspects of each study such as methodology and findings.

Annotated bibliographies are sometimes given as a task at the beginning of a research topic. It is to gain a perspective on what is being published about a topic and subsequently assist in writing a literature review.
