- PARADIGMS, THEORY, AND RESEARCH
2Dictionary definitions (from Hypertext Webster
Gateway)
- Deduction That which is deduced or drawn from
premises by a process of reasoning an inference
a conclusion - Induction The act or process of reasoning from a
part to a whole, from particulars to generals, or
from the individual to the universal also, the
result or inference so reached
3Definitions from Babbie text
- Deduction the logical model in which specific
expectations are developed on the basis of
general principles - Induction the logical model in which general
principles are developed from specific
observations

6Deduction and Induction on the Wheel of Science
7Defining concepts from the Wheel (definitions
from Babbie)
- Theories - systematic explanations for the
observations that relate to a particular aspect
of life sets of propositions explaining a
phenomenon - Hypotheses - expectations about the nature of
things derived from theories a statement of
something that ought to be observed in the real
world if the theory is correct. Variables are the
building blocks of hypotheses.
8- Observations - the process of information
gathering or data collection in research. - Empirical Generalizations - conclusions based on
the results of data analysis, either qualitative
or quantitative.

expectations are developed on the basis of

11A social scientific example of the deductive
method
- Identify a topic of interest e.g., occupational
success - Develop your theory on the basis of prior social
scientific theory or create a new theory - The theory should address why some people are
more successful in their occupations than others.
12- Specify your major variables e.g., level of
education, gender, income, level of occupational
prestige - Derive one or more testable hypotheses
- Conduct research, collect observations, and
analyze data - Consider the theoretical implications of your
empirical results
13How to develop hypotheses
- Clearly identify independent and dependent
variables - Develop a logical argument for an IV-DV
relationship - Specify the nature of the expected relationship
(next 4 slides)
14Nature of the expected relationship (1)
- (1) Quantitative IV DV
- Positive/Direct IV?DV? and IV?DV?
- Level of formal education will be positively
related to level of occupational prestige, with
people at higher levels of formal education
having higher levels of occupational prestige. - Negative/Indirect IV?DV? and IV?DV?
- Level of formal education will be negatively
related to level of prejudice, with people at
higher levels of formal education having lower
levels of racial prejudice.
15Nature of the expected relationship (2)
- (2) Non-quantitative IV Quantitative DV
- Certain categories of IV will have higher values
of DV. - Gender will be related to level of church
attendance, with females will having higher
levels of church attendance than males. - Certain categories of IV will have lower values
of DV. - Religious affiliation will be related to
attitude toward abortion, with Catholics having
lower levels of approval of abortion than those
in other religious groups (Protestants, Jewish
people, other religion, no religious affiliation).
16Nature of the expected relationship (3)
- (3) Quantitative IV Non-quantitative DV
- Higher values of IV will fall into certain
categories of DV. - Level of job satisfaction will be related to
whether people would continue to work if rich,
with those at higher levels of job satisfaction
being more likely to say they would continue to
work if rich than people at lower levels of job
satisfaction. - Lower values of IV will fall into certain
categories of DV. - Age will be related to attitude toward capital
punishment, with younger people being less likely
to favor capital punishment than older people.
17Nature of the expected relationship (4)
- (4) Non-quantitative IV and non-quantitative DV
- Certain categories of IV will fall into certain
categories of DV. - Gun ownership will be related to attitude toward
mandatory firearms registration, with people who
own guns being less likely to favor mandatory
firearms registration than people who do not own
guns. - Whether or not people have children will be
related to type of vehicle owned, with people who
have children being more likely to own mini-vans
than those who do not.
18Hypothesis development using the GSS
- General Social Survey Codebook
- On left, use Mnemonic link if you know the
variable name(s). - On left, use Subject link if you are trying to
find variables that would be relevant to a
particular topic.
19Induction the logical model in which general
principles are developed from specific
observations
Observations
Empirical Generalizations
Theory

(a, b, c).
21A social scientific example of the inductive
method
- You want to find out who likes coed dorms better
- women or men. - You gather data. What specific behaviors or
statements made by people might you be able to
observe that would be relevant to your research
question? - You analyze your data. Hypothetical results
women like coed dorms better than men do. - Based on your results, what theory could you
develop that might account for this? Why do
women like coed dorms better?
22Deduction/Induction - Which is better?
- Deduction is often viewed as more scientific,
because hypotheses are tested. - However, see Wheel of Science (next slide) both
are important parts of the scientific process. - Induction is most often used in exploratory
phases of research and deduction in confirmatory
phases.
