of 2
October 19 – conceptualization, operationalization, and measurement
Test 1
Chapter 1 to Chapter 5 (pages 35-43 in Chap 2 are not included in the test; look at new book**)
3 parts
Multiple Choice
True and Falseif false, give correct statement
Short Answer (general themes/discussions)
Terms and Concepts
-To generate a common agreement of terms/concepts
-The process: conceptualization
-End product: concepts
-Why do we need common definition of a concept?
oDiscussion is possible
oKnowledge can be accumulated
Characteristics of conceptualization
- Indicator
oSign of the presence or absence of the concept
oi.e. when we think about how many people passed a test, we look at how many people
scored above 50
oConcepts are refined into different distinguishable concepts
oi.e. when thinking of minority groups, we usually think about ethnicity as a way to define;
others might disagree and think about religiosity
ooperational definition
to specify how a concept is to be measured
-Range of variation – (i.e. when studying property value in Toronto, using proper ranges is critical
400k+ top is not the best option)
-Dimension – depends on how you capture the concept
-Levels of measurements
oNominal(i.e. do you belong/not belong to the group)
oOrdinalthe ranges between very important and important are vague; lack of
information (i.e. strongly agreestrongly disagree)
oIntervaldanger is that there is no absolute zero**
oDepend on (1) concept used; (2) data availability
Criteria of measurement quality
-Precision talking about an issue in a specific context so that it is interpreted properly
-Reliability – being able to obtain the same results when applying the same measurements;
ensuring measurements are reliable
oUsing established measureusing measures that have been created by established groups
oFace validity – by looking at the question itself, it will tell you if the measurement is valid
or not
oCriterion-related validity (predictive validity)based on predictive power; i.e. GRE,
LSAT, MCAT for graduating studies
oConstruct validity – based on relationships among variables (i.e. job satisfaction based on
relationships with boss, clients etc)
oContent validity – how much a measure covers a range of meanings
