Quantitative Analysis 1
1. Quantitative analysis:
---------
e.g. relationship between job insecurity and health can be investigated by collecting "Numerical representation
and manipulation of ob-
servations for the purpose of describing the phenomena that those observations reflect"
EX. individual's reports of job insecurity and their mental health, coding these responses numerically, and then analyzing
with statistical software
2. Quantification:: Converting data to a numerical format
3. Quantification
- This allows data to be recorded on a
for storing information that can be read by a
- You quantify
- This allows us to do on them
- Quantification requires a standard procedure for coding the raw data: a
: - computer or some other device
- computer for analysis.
- non-numerical data (assign numbers to them)
- calculations
- codebook
4. Coding Data:: Coding or assigning numbers to information (in many cases the numbers we assign are arbitrary
BUT we need to do it systematically)
- EX. Gender (1=M; 2=F)
- EX. Religious affiliation (1=Roman Catholic, 2=Evangelical Protestant, 3= Liberal Protestant, 4=Mormon,
5=Muslim, etc.)
- EX. Job Insecurity (1="Not at all likely"; 2="Somewhat likely"; 3="Very likely")

schemes
- open-ended responses
7. Codebook Definition:: The document used in data processing and analysis that tells the location of different items in
the data file.
8. Codebook
- Typically, the codebook identifies

- meaning of the codes
- attributes of variables.
- Variable name, variable label (definition), values (attributes), value labels, missing values
9. · DK means and REF means
o For DK and REF in age you would not use the numbers because it could be
possible that they are (in this case we
would say ): - don't know
- refused
- 98 or 99
- 89/99 in age
- 999 for DK and 998 for REF
