2. Theories, Hypotheses, and Operational Definitions (17)
Building Blocks of the Research Process:
Theory: Concept 1 is related to Concept 2
Hypothesis: Variable 1 is related to Variable 2
Operational Definition: How you measure variable 1 and variable 2.

3. Theories, Hypotheses, and Operational Definitions (17)
Theory
It is a set of empirical generalizations about a topic. It is too general to test since it makes statements about the relationship between abstract concepts. To test a theory, it has to be brought down to more specific terms. (17)
Hypotheses
This is done by testing hypotheses, which is an empirical statement derived from a theory. They are statements about variables.

4. Theories, Hypotheses, and Operational Definitions (17)
Variables: (19)
They are empirical properties that can take on two or more different values.
Operational Definition
But even variables are not specific enough. Each variable in a hypothesis must have an operational definition, that is, a set of directions as to how the variable is to be observed and measured.

5. Types of Hypotheses (19) Types of Hypotheses:
Univariate: making a statement about only one property or variable. (19)
Multivariate: a statement about how two or more variables are related. Most hypotheses are multivariate and
Directional: that is, they suggest not only how the variables are related
but what the direction of the relationship is. (19)
Null Hypothesis: There is in fact no relationship between the stated independent and dependent variables.

6. Hypothesis Hypothesis: Variables
(IV) Independent Variable: the cause of something
(DV) Dependent Variable: the effect
It is not always easy to determine the IV and DV.
Control Variables: when they are used the intent is to ensure their effects are excluded. …

7. Types of Hypotheses (19)
Types of Directional Relationships: Positive/Negative
Positive: variables move in the same direction:
Example:
1. As income rises, so does voting,
2. As income drops, so does voting.
Negative (or Inverse): Variables move in opposite directions:
1. As income rises, homelessness drops.

8. EXAMPLES: Levels of Research: (18)
Hypothesis:
IV: Cause DV: Effect
Positive:
IV: Cause DV: Effect
They go up together.
They go down together.

9. EXAMPLES: Levels of Research: (18)
Hypothesis:
IV: Cause DV: Effect
Negative:
IV: Cause DV: Effect
The variables move in opposite directions. They have an inverse relationship to each other .

10. Operational Definitions (25)
Testing a hypothesis requires precise operational definitions specifying how each Variable will be measured. If a variable cannot be operationally defined, it cannot be measured.
Operational Definitions: Two Requirements:
1) It must specify what we want to know
2) And where (or how) we will get that information.
Example:
Say we want to examine ethnic diversity in Boston: What we want is how people in Boston identify ethnically, and how we would get it would be to look at the most recent US census data on Boston.

11. Units of Analysis (22) Two common Units of Analysis: (26)
Individuals: indicates either people in general, or a specific type of
person (elected official, union member, etc). It can also refer to
institutions, such as interest groups, corporations, political parties. What
you are doing is looking at how an “individual” unit, a person, a party is
behaving. Polls are the best source of data on people in general, whereas
their can be other sources of data on specific classes of individuals. (26)
Groups: analyze group behavior, such as performance on some test. You don’t go down to the individual. How did Democratic state legislators vote on a particular issue, as a group? You use aggregates, as opposed to individual data points.
It is not always easy to determine the unit of analysis. Yet the choice of which unit to use is extremely important. (22)

12. Units of Analysis (22)
Units of Analysis: Exam Scores Individuals: Student Score Compare to: Other Students
Groups: Average Class Score
Compare to: Other Classes
Student: 85
Class: 90

13. Units of Analysis (22)
Units of Analysis: Political Parties Individuals: Dem. Or Rep. Party Compare to: Other Parties
Groups: Party System
Compare to: Other Party Systems
Democrats
Amer. Party System
Republicans

14. Ecological Fallacy: (22-23)
Ecological Fallacy erroneously drawing conclusions about individuals from groups. Solution: only draw conclusion about the units of analysis from which the data is actually drawn.
Example of Ecological Fallacy: Afro-Americans and Wallace
Student found a strong positive (directional) relationship between proportion of a county that was Afro-American and those that voted for George Wallace and assumed Afro-Americans voted for Wallace. (22-23)
In fact, virtually no minorities supported Wallace. All the student really could say is that counties with a high number of Afro-Americans voted for Wallace. The county, not Afro-Americans was the unit of analysis.

15. Units of Analysis (22) Individuals: Voters Compare to: Other Voters
Units of Analysis: Votes for Wallace
Counties, not necessarily Black voters supported Wallace.
Individuals: Voters Compare to: Other Voters
Groups: County
Compare to: Other Counties
Black
Supported Wallace
Black
White

Hypothesis: The more industrialized a nation, the greater the level of mass political participation.
Null: There is no relationship between industrialization and mass participation.
Operational Definition: The higher percentage of manufacturing jobs (IV), as measured by United Nations Yearbook, the higher the percentage of people who voted (DV) in the last national election, according to the Stateman’s Yearbook. …
