Theory explains how or why a phenomenon is expected to occur; methodology is the reasoned approach used to investigate a question. In a college research project, theory helps shape what you ask and how you interpret findings, while methodology explains how you will gather and analyze evidence. Why the distinction matters The terms are related, […]

A concept is an idea or category used to describe something, while a theory is an organized explanation of how or why something happens. In college courses, concepts are often the building blocks of theories: a theory connects concepts and evidence to explain patterns or make predictions. What Is a Concept? A concept is an

A scientific fact is an observation or measurement that has been repeatedly confirmed; a scientific theory is a well-supported explanation for facts and other evidence. A theory is not a guess waiting to become a fact: facts describe what is observed, while theories explain how or why observations occur. What Does “Fact” Mean in Science?

Qualitative research explores meanings, experiences, and processes, usually through words or observations; quantitative research measures variables and analyzes numerical data. Mixed methods deliberately combines qualitative and quantitative approaches in one study so that each can address a different part of the research question. What the Three Approaches Mean These terms describe broad approaches to research,

Qualitative content analysis and thematic analysis are both ways to identify patterns in qualitative data, but they organize and interpret those patterns differently. Content analysis usually develops categories for describing or interpreting what appears in the material, while thematic analysis builds themes that capture meaningful patterns across a dataset. What the Two Methods Have in

Qualitative observations describe qualities or characteristics using words, while quantitative observations express amounts or measurements using numbers. In college science and research methods, the difference is whether an observation records what something is like or how much, how many, or how often. What Is a Qualitative Observation? A qualitative observation records a feature that is

Qualitative data describe qualities, categories, meanings, or experiences, while quantitative data represent amounts that can be counted or measured numerically. In research, the difference is not simply whether information contains numbers: it is what the information represents and how the researcher can analyze it. What Qualitative Data Means Qualitative data record what something is like

In research, a primary source provides direct evidence or an original account of the subject being studied, while a secondary source interprets, analyzes, or summarizes evidence from primary sources. The distinction depends on your research question and how a source relates to it—not simply on whether the source is old, scholarly, or published. What Is

Primary data is information a researcher collects firsthand to answer a particular question; secondary data is information someone else has already collected, usually for another purpose. The key difference is not whether the information is numerical or descriptive, but who collected it, why it was collected, and how well it fits the current study. What

A scholarly source is written for an academic audience and contributes to or discusses knowledge in a field; a peer-reviewed source is a scholarly work that has been evaluated by subject experts before publication. The terms overlap, but they are not interchangeable: many peer-reviewed articles are scholarly, while scholarly books, conference papers, and other academic
