Validity is a concept most easily identifiable with quantitative research
Term has a wide range of possible meanings in the field of research methods, but the central
idea revolves around accuracy and truthfulness
Different types of validity (quantitative research)
Measurement validityfor a measurement to be valid, if it accurate represents the concept
that it is intended to operationalize.
o Face validity is one aspect of measurement validity. “common sense validity”
Does the measure we are using seem like it should be used as a measure?
o E.g. Which has a greater face validity for “animal rights activism” : someone who owns a
pet or an individual; who donates to animal shelters?
Someone who owns a pet can beat their pet. Hence the individual who donates
to animal shelters is better.
Indicators are said to be “divergently valid” if the variables are thought to be indicators of the
same measure- but have reverse directionalities- and they yield opposing results for most cases.
o Indicator vs. measure
Difference is that we can use multiple indicators to construct a measure.
An indicator is only ONE component of a measure.
o E.g. the indicators “support for same sex marriage” and “opposition to abortion rights”
are said to have “convergent validity” if they are thought to be indicators of a measure
of “moral traditionalism” and they yield similar results for most cases.
External validity-findings are generalized from the sample included in analysis to cases outside
of the sample.
Internal validity-A study internally in itself makes sense.
Qualitative research is said to be credible if the data used in the qualitative account fits the
world being described; the qualitative account must be believable.
Qualitative research is said to be transferable if the findings can
