Internal vs external validity

When testing cause-and-effect relationships, validity can be split up into two types: internal and external validity.

Internal validity refers to the degree of confidence that the causal relationship being tested is trustworthy and not influenced by other factors or variables.

External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events.

The validity of a study is largely determined by the research design: what, how, where and when the study was executed. To ensure the validity of the tools or tests you use, you also have to consider measurement validity.

Inductive vs. deductive reasoning

The main difference between inductive and deductive reasoning is that inductive reasoning aims at developing a theory while deductive reasoning aims at testing an existing theory.

Inductive reasoning moves from specific observations to broad generalizations, and deductive reasoning the other way around.

Both approaches are used in various types of research, and it’s not uncommon to combine them in one large study.

Qualitative vs. quantitative research

There are two approaches to collecting and analyzing data: qualitative research and quantitative research. Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.

Each of these types of research has different objectives and methods, and both are important for gaining different kinds of knowledge.

Quantitative research

Quantitative research is expressed in numbers and graphs. It is used to test or confirm theories and assumptions. This type of research can be used to establish generalizable facts about a topic.

Qualitative research

Qualitative research is expressed in words. It is used to understand concepts, thoughts or experiences. This type of research enables you to gather in-depth insights on topics that are not well understood.

APA in-text citation

APA in-text citations (6th edition) consist of the author’s last name, publication year and, if applicable, page numbers. Page numbers are required when quoting and encouraged when paraphrasing. Omit page numbers when referring to a source as a whole.

In-text citation can be included in multiple ways:

  • The author claims that “plagiarism is becoming a bigger problem” (Smith, 2014, p. 170).
  • Smith states that plagiarism is an increasingly big problem (2014, p. 170).
  • The study of Smith (2014) shows that plagiarism is an increasingly big issue.

You can easily generate your in-text citations (and full reference list) in APA format with Scribbr’s free citation generator.
