Reliability vs Validity in Research | Differences, Types ...

In quantitative research, you have to consider the reliability and validity of your methods and measurements. Validity tells you how accurately a method measures something. If a method measures what it claims to measure, and the results closely correspond to real-world values, then it can be considered valid.

In simple terms, validity (also called "construct validity") is all about whether a research instrument accurately measures what it's supposed to measure. For example, let's say you have a set of Likert scales that are supposed to quantify someone's level of overall job satisfaction. If this set of scales focused purely on only one ...

Validity in Research and Psychology: Types & Examples

This article describes the basic tenets of quantitative research. The concepts of dependent and independent variables are addressed and the concept of measurement and its associated issues, such as error, reliability and validity, are explored. Experiments and surveys - the principal research designs in quantitative research - are described ...

What Is Quantitative Research? | Definition, Uses & Methods

Internal validity examines whether the study design, conduct, and analysis answer the research questions without bias. External validity examines whether the study findings can be generalized to other contexts. Ecological validity examines, specifically, whether the study findings can be generalized to real-life settings; thus ecological ...

Validity 1 VALIDITY OF QUANTITATIVE RESEARCH Recall "the basic aim of science is to explain natural phenomena. Such explanations are called theories" (Kerlinger, 1986, p. 8). Theories have varying degrees of truth. Validity is the best approximation to the truth or falsity of propositions (Cook & Campbell, 1979).

As with the nature of quantitative research, there is a defined approach or process for establishing validity. This also allows for the findings transferability. For a study to be valid, the evidence must support the interpretations of the data, the data must be accurate, and their use in drawing conclusions must be logical and appropriate.

Internal validity makes the conclusions of a causal relationship credible and trustworthy. Without high internal validity, an experiment cannot demonstrate a causal link between two variables. Research example. You want to test the hypothesis that drinking a cup of coffee improves memory. You schedule an equal number of college-aged ...
