Class 2 - Social Structures and Interaction Flashcards
Experimental Designs
Directly manipulates variables
-Random Sampling
-Random Assignment
-Control of extraneous variables
-Manipulation of treatment
Extraneous variable
Something not being tested that can effect the outcome of the experiment
ex.) time of year, color of uniforms
Non-Experimental Designs
Variables are not directly manipulated
-Ethnographic Studies
-Twin Studies, Heritable studies
-Archival Studies, Biographical Studies
-Phenomenological Studies
-Observational studies
-Case studies
-Longitudinal Studies
Ethnographic Study
The researcher immerses themselves in the community to observe something; cultural immersion
Archival Study
Use records and research from the past
Biographical Study
Interviewing people or using records from the past
Phenomenological Study
A study that looks at a certain phenomenon
ex. impact of quarantine or schooling from home on children
Observational Study
The researcher does not make themselves known or intervene, but observes something
Case Study
Looking at one or two individuals, or one individual at a time
Longitudinal Study
Long-term study over years or decades
Between Subjects experimental design
Comparing different individuals or groups
Within Subjects experimental design
Multiple measures of the same individuals to groups; comparison within a group
ex. cortisol levels on a group that watched a horror movie at different times
Quantitative experimental design
Provides numerical results
Qualitative experimental design
Provides descriptive information
ex. what people say or write
Mixed Methods experimental design
Using between and within subjects design; Using qualitative and quantitative methods; Using several methods to see differences
Repeated Measures
Measuring something specific repeatedly over time
ex. within subjects design
Quasi-Experimental Method
There is no control group; usually just one group at different time points, possibly having multiple measures
Comparative Method
Looking at existing groups/studies; groups cannot be created
ex. smokers vs non-smokers (can’t make people smokers)
Internal Validity
Can conclude to a degree that the independent variable is responsible for the outcome;
extent to which the outcome variable is due to the intervention
ex. continue testing people and keep seeing same results = high internal validity
5 Common Threats to Internal Validity
- Impression Management
- Confounding Variables
- Lack of Reliability
- Sampling Bias
- Attrition Effects
Impression Management
Participants of an experiment adapt their responses based on social norms or perceived researcher expectations; self-fulfilling prophecy; methodology is not double blind; Hawthorne effect
Confounding Variables
Extraneous variables not accounted for in the study; another variable offers an alternative explanation for results; lack of a useful control
ex. age, gender
Lack of Reliability
Construct validity; measurement tools do not actually measure what they proper to measure; lack consistency
Sampling Bias
Selection criteria is NOT random;
Population used for sample does not meet conditions for statistical test
Population is not normally distributed/ NOT randomly sampled
ex. Stanford Prison Study - people were volunteers
Attrition Effects
Participants drop out of study;
Participant fatigue
Hawthorne effect
People know they’re being watched and will alter behavior because of it
Construct Validity
Whether the thing you’re proportion to measure is actually measuring that thing
ex. measuring depression with a survey
External Validity
AKA Experimental Generalizability
Extent to which the findings can be generalized in the real world
4 Common Threats to External Validity
- Experiment doesn’t reflect real world
- Selection Criteria
- Situational Effects
- Lack of statistical power
Experiment doesn’t reflect real world
Laboratory setups don’t translate into the real world;
lack of experimental generalizability
Selection Criteria
too restrictive in inclusion/exclusion criteria for participants;
sample is not representative
Situational Effects
Presence of laboratory conditions changes outcome
ex. pre- and post-test, presence of experimenter
Lack of Statistical Power
sample groups have high variability or the sample size is too small
Validity vs Reliability
Reliability - How repeatable something is; how much it can be trusted
Validity- Measuring the thing you say it’s measuring; How correct it is
Reliability
Consistency, repeatable
Validity
Does it measure what it claims to measure
Beck Depression Inventory
-One of the most common instruments used to measure depression
-Highly reliable- taking it twice will give similar score
-Highly valid- a high score indicates the person likely has depression
Social Institutions
Standardized set of social norms organized to preserve a societal value
5 Core Social Institutions
- Family
- Education
- Government, Economy, and Politics
- Religion
- Health/Medicine
Stability of social institutions helps prevent what?
Anomie - occurs when societal values do not adequately guide the individual or group behavior
Education as a social institution
a formal process whereby knowledge, skills, and values are systemically transferred from one individual or group to another
-provides mass literacy and more opportunity
Hidden Curriculum
Unintentional lessons about norms, values, and beliefs
-Things taught by example
Ways education promotes equality
-avg years of schooling and income inequality have a neg. correlation
-more education associated with less inequality
Ways education promotes inequality
-Hidden curriculum
-Teacher expectancy
-Educational Stratification
-Educational Segregation
Teacher expectancy
Teachers’ expectations shape the students’ behaviors
Educational Stratification
Ranking students based on their level of academic achievement
Educational Segregation
When education is different depending on the neighborhood based on the wealth in the neighborhood
Family as a social institution
relates individuals by a socially-defined set of relationships like birth, adoption, and/or marriage
Which sociological theory best explains the usefulness of family to society?
Functionalism
Religion as a social institution
involves beliefs and practices related to the sacred
