Qualitative and quantitative
measurement
SHAKEELA ASGHAR
MS SOCIOLOGY FROM IIUI
BS SOCIOLOGY FROM IIUI
The measurement process:
 When we measure, we connect an invisible concepts or ideas in our
minds with a technique process with which we observe the ideas in the
empirical world.
 In quantitative studies we start with abstract ideas and end with
empirical data.
 In qualitative studies we mix ideas and data while gathering data.
 We use two process in measurement :
 conceptualization & operationalization.
Conceptualization:
 Conceptualization is taking an abstract construct and refining it by
giving it a conceptual and theoretical definition.
 Conceptualization is basically a statement of any idea in your mind in
specific world or term that are linked with others ideas and constructs.
 It’s not a magical way to construct , its involve thinking carefully,
observing directly, consulting with others , reading the articles what
other said or describe and then finally trying to make possible definition
by your self with the help of old literature and observing.
 the definition must be clear, explicit and have specific meaning.
 Conceptualization is highly creative and produce new directions.
Conti…..
 A single construct have several definition.
 Conceptual definition linked to theoretical framework.
 Some concepts are highly abstract and complex others are concrete
and simple. As a researcher we aware of how complex abstract a
construct is.
 We need three things in measurement process:
a construct
a measurement
a ability to recognize what we are looking for
Operationalization:
 The process of moving from a construct conceptual definition to
specific activities or measures that allow a researcher to observe it
empirically.
 Its could be a survey, questionnaire, a method of observing events in
field setting , content analysis or any other process that reflect or
represent the abstract, construct as its expressed in the conceptual
definition.
 Theory has many abstract concept, assumption and cause and effect
relationship by contrast empirical measure are very concrete action in
specific real situation with actual people and event.
conti…
 Operationalization connect the language of theory with the language of
empirical measure.
 Measures are specific to the operation we engage into indicators the
presence or absence of a construct. Its exists in concrete through
observation and techniques.
Quantitative
conceptualization and
operationalization
Quantitative conceptualization and
operationalization
 Quantitative measurement procedure in a sequence first
conceptualization, next operationalization and then the collection of
data.
 We link abstract ideas to measure procedure that produce information or
result in a form of numbers.
 One way to do this with the rules of correspondence.
 Rules of correspondence are standards that researcher use to connect
abstract constructs with measurement operation in empirical social
reality.
Conti…
 When we measure, we link the three level together and move deductively from
the abstract to concrete.
 We consider the three levels :
conceptual
operational
empirical
 First, we conceptualize the variable giving it clear conceptual definition.
 Next, we operationalize it by developing an operational definition or set of
indicator for it.
 Lastly, we apply indicators to collect data and test empirical hypothesis.
Conti..
 At the conceptual level we are interested in the casual relationship
between the variables that is called conceptual hypothesis.
 Conceptual hypothesis: a type of hypothesis that express variable and
the relationship among them in abstract and conceptual term.
 At operational level we are interested in testing empirical hypothesis.
 Empirical hypothesis: determine the degree of association between
indicator. At that level we consider correlation, statistics and
questionnaire.
Conti…
 The third level is the empirical reality of the lived social world.
 At that stage we capture what is taking place in lived social world and
then relate back to the conceptual level.
 Conceptualization and operationalization are necessary for each
variable.

Conceptualization in qualitative:
 In qualitative research we didn’t refine abstract idea early into
theoretical definition. We refine it during data collection and analysis
process.
 After gather and analyze qualitative data we develop new concepts,
formulate definition for major constructs and relationship among them.
 We link concept to create theocratical relationship.
Conti…
 We form and refine concept while examine data and ask theoretical question
about the data.
 We need clear definition and express them in words and description of specific
actions that linked to other ideas and are tried to data.
 In qualitative research conceptualization flaws largely from the data.
Conti…
 Operationalization in qualitative research:
 In qualitative research operationalization largely involve creating a
description of how we use working ideas and concepts during
observation.
 Operationalization describe how we gather data through observation
and try to understand the data as the data evolved into abstract to
concrete.
 Qualitative operationalization include using preexisting techniques and
concepts that we blend with those that emerged during the data
collection.
Casing:
 In qualitative research ideas and evidence are mutually interdependent.
 This applies particularly to case study analysis.
 Cases are not given before empirical units we defined it by theory and
data.
 After analyzing the situation, researcher organize a data and applies
ideas to create case.
 Developing cases in qualitative research is called casing.
 It brings the data and theory together.
