Observation is
|
the foundation of empirical research
|
|
Observation is done through
|
measurement
|
|
Measurement is
|
careful, deliberate observation of the real world to describe objects and events and processes
|
|
How we measure affects our
|
results
|
|
Direct observables
|
what you can see and record yourself; physical characteristics (sex, age) being observed
|
|
Indirect observables
|
think archives and secondary sources and retold information; characteristics of a person given in a self-administered questionaire
|
|
Studying what you can't see
|
how do you measure love and prejudice? You can't see it. Personal experience in defining constructs
|
|
Constructs
|
o How we measure what we can’t see.
o Level of alienation, as measured by a scale that is created by combining several direct and/or indirect observables. o Theoretical creations that are based on observations but that cannot be observed directly or indirectly. |
|
personal experiences
|
shape our social understandings of terms
|
|
indicator
|
an observation that we choose to consider as a reflection of a variable we wish to study. For example, attending religious services might be considered an indicator of religiosity.
|
|
Identity as 3-dimensional construct
|
cognitive (what to know)...behavioral (acting a certain way)..affective (how we feel about it)
|
|
Let’s say we wish to measure TV violence in more than one way. We could operationally define
|
Type of violence (sport vs torture)…Length of scene (time)…Victim reaction…Outcome of event
|
|
Social scientists can measure anything that’s real through
|
conceptualization and operationalization.
|
|
Law of parsimony
|
How much detail do I need? What range of variation am I measuring? Ask what you need—no more and no less. What is your research question?
|
|
Operational definition
|
defining terms until they work. specifies precisely how a concept will be measured. that is, the operations we will perform.
|
|
Nominal/Categorical Definition
|
one that is simply assigned to a term without any claim that the definition represents a “real” entity. They are arbitrary.
o Gender, religious affiliation, political party affiliation, birthplace, college major, and hair color. |
|
Conceptual Definition
|
produces a specific, agreed-on meaning for a concept for the purposes of research.
|
|
Attributes
|
characteristics or quality of an object or person
|
|
Variable
|
Logical set of attributes that vary across a population
|
|
Ordinal
|
Relative ranking among categories. Distance between scale points not known
|
|
Interval
|
Known distance between scale points. No absolute zero.
Distance in Fahrenheit and IQ scores. |
|
Ratio
|
Interval scale with absolute zero.
A level of measurement describing a variable with attributes that have all the qualities of nominal, ordinal, and interval measures and in addition are based on a “true zero” point. Age, number of times married |
|
General rule: the higher the level of measurement
|
the more sophisticated your statistics can be
|
|
Population
|
complete list of persons or objects we want to study.
|
|
Sample
|
a subset of population.
|
|
Representativeness
|
how closely a sample matches it's population in terms of the characteristics we want to study.
|
|
Sampling error
|
degree to which a sample's characteristics differ from the populations characteristics.
|
|
Probability sampling
|
more rigorous because it means every single person of the population has an equal chance of being part of that sample. when possible we do this.
|
|
Non probability sampling
|
- Reliance on available subjects: sometimes called “convenience” or “haphazard” sampling. Can provide useful insights but we must be careful not to overgeneralize from them. Does not give control over the representativeness of the sample.
|
|
You want to be able to draw conclusions from your analysis that
|
can be applied to the population of interest.
|
|
Convenience sampling
|
use who is most closely available as participants.
|
|
Volunteer sampling
|
students who get extra credit for participating in campus research projects (ethical issue).
|
|
Purposive or quota sampling
|
selecting a certain number of particular kind of people (proportions/types).
|
|
Snowball sampling
|
start with one participant and snowball out to include their references/friends.
|
|
Systematic sampling
|
choosing every nth person in a population when you know how many people you need to contact.
|
|
Stratified random sampling
|
dividing the population along a certain characteristic of interest to the research and then randomly sampling from each group.
|
|
EPSEM: stands for equal probability of selection method.
|
Each member of a population has the same chance of being selected into the sample.
|
|
Cluster sampling
|
random sampling of location...not the people themselves...then sampling people at that location.
|
|
Multistage sampling
|
used to deal with very large populations...when using a sampling frame is not feasible. Probably the most complex of probability sampling.
|
|
What are the two most important ways that you find out health-related information?
|
random digit dialing of all numbers to reach a specific ethnic group in a specific LA community and a nationwide survey conducted online with people who have been recruited by Knowledge.
|
|
Why is random selection important
|
increases our confidence that the sample we've collected is like the whole population
|
|
Marriage in america: who conducted the study
|
pew research center. Trusted research facility
|
|
Marriage in america: who funded the study?
|
pew charitable trusts
|
|
Marriage in America: who else contributed to the research?
|
academic experts
|
|
Marriage in America: how was the population sampled
|
gives dates...telephone survey of adults 18 and older
|
|
What is the instrumental value of marriage in America
|
common law marriage...health benefits...social recognition of marriage if you don't believe in it?
|
|
Why definitions matter
|
- replication: repeating a study and checking to see if the same results are produced each time.
- Allows other researchers to assess similarities and differences in findings with other research projects - can advance political arguments - determines the nature of possible responses |
|
Conceptualization
|
mental process whereby fuzzy and imprecise notions are made more specific and precise result is called a concept
|
|
Dimension
|
specific aspect of a concept (breaking it down into other dimensions)
|
|
Specification
|
process through which concepts are made more specific
|
|
Validity
|
a measure that accurately reflects the concept it is intended to measure
|
|
Face validity
|
quality of an indicator that makes it seem a reasonable measure of some variable.
|
|
Criterion
|
related validity
|
|
Construct validity
|
degree to which a measure relates to other variables as expected within a system of theoretical relationships
|
|
Content validity
|
a measure cover s the range of meaning included within a concept
|
|
Vulnerable populations
|
might be considered vulnerable when they have relatively less power in the broader political context as well as in the research process;making them more susceptible to exploitation ex. Prisons or psych wards;students and children;people with free material resources or social privileges
|
|
Periodicity
|
may limit the process if a potential pattern in the listing that would create a sample not typical of the population
|
|
Focus groups
|
may be selected purposively by the researcher
|
|
Sampling bias
|
that the people or texts constituting the research sample are not typical of the broader population they are meant to reflect.
|
|
External validity
|
relationship between the particular research project and the wider context in which it was conducted
|
|
Research implementation
|
the process of gathering and assessing data
|
|
Participant observation
|
might work directly with the research subjects or watch from a distance without engaging in the activities
|
|
Interviewing
|
subjects directly;whether through open-ended or more structured formats;can focus on individual informants or on groups;either through focus groups and shiz
|
|
Assent
|
consent given by an adult to children
|
|
Public Space
|
Researchers may believe they can ignore procedures toward ensuring informed consent when research subjects are in a public setting. Distinction between public and private space is not always clear ex. Internet forums and shiz like that
|
|
Video cameras
|
assessing visual as well as verbal cues
|
|
Audiotape
|
attention to inflection and most importantly would offer a complete record of each word said
|
|
Consider how researchers have documents their observations
|
using alternative approaches to documentation offered different kinds of information
|
|
Action research
|
research participants should have control over the purpose and process of the research;relative to the researchers
|
