Experiental Reality
things we know from DIRECT experience - anecdotal
ex: touching hot stove
Agreement Reality
things we think are real because we’ve been told they are and everyone agrees
ex: Santa
Practitioner Lens
rely on “Professional Intuition”
research methods allow them to test their intuition against data to see if their “reality” matches results
UCR (Unified Crime Report)
A database that shows crime based on crime records
Personal Human Inquiry
curious species about the future and the world around us
the goal: to predict the future circumstances based on current patterns (fantasy football)
Causal reasoning
Cause and Effect
ex: Main Street Bridge will be late cause of traffic
Probalistic reasoning
likelihood, not certainty
ex: backroads usually quicker but school buses could slow it down
Inaccurate Observation
Error for reasoning
daily are casual; science make observation deliberate
Overgeneralization
error for reasoning
assuming few similar events are evidence of similar pattern
Selective observation
error for reasoning
focused on future events that fit pattern we already identified
Illogical Reasoning
error for reasoning
A gamble not support by facts
Hypothesis
starts all experiments
is the question you are trying to answer
Exploration Research (1 of the 4 purposes)
new or understudied phenomenon (widenet)
Description Research (1of the 4 purposes)
documenting scope of problems (UCR)
state-of-the-agency reports
Explanation Research (1 of the 4 purposes)
Why does this happen?
reporting relationships w/ variables
Application Research (1 of the 4 purposes)
uses policy analysis
did the evaluation research work.
predicting if a new policy will work and applying to people
Logic
rationality
do these things make sense
Attributes
characteristics or qualities that make up a variable
ex: sleep duration - the QUALITY of how many hours of sleep gotten
Variable
made up of attributes
Logical grouping (Dem or Rep)
ex: the NUMERICAL VALUE of representing sleep duration (5, 6, or 7?)
a measurable quantity
Quantitative Data Analysis
statistical, hard numbers, broad nomothetic research
heavy for CRJ research
Qualitative Data Analysis
Non-numerical, journalism, small sample size
“richness” idiographic research
Qual is less scientific
Nuremburg Code (1947)
concentration camps post WWII - seeing if voluntary consent is mandatory in medical experiments
Tuskegee Syphilis Study (1932-1972)
U.S Pub Health untreated syphilis in 60 black males and withheld the information that they had syphilis. Exploitation of disadvantaged groups
Belmont Report (1979)
response to Syphilis study, provides core ethics
no harm to participants, voluntary participation & informed consent, Anonymity vs. confidentiality, Deception and Historical Misbehavior
Standford Experiment (1971)
Lord of the Flies type situation
24 male college students were assigned as “guards” or “prisoners” in a mock prison at Stanford University. only lasted 6 days
Milgram Obedience Study
WWII based.
How soldier obedience happened with authority
teacher was instructed to administer increasingly severe electric shocks to the learner whenever an incorrect answer was given. The shocks were fake, but participants believed they were real. The shock generator ranged from 15 volts to 450 volts, with labels escalating from “mild” to “danger: severe shock”
this cause psychological harm to participants since information was withheld
No Harm
No physical, emotional, and psychological harm (stress, anxiety)
physical harm rare in Social Science
Social/Legal Harm
major risk in CJ
a “snitch” affects social status
Voluntary and Informed Consent
understand risk, benefit, and rights
not mandatory reporters unless dealing with Juveniles
prisoner dilemma: can inmate truly say not?
DO NOT offer incentives
Anonymity vs. Confidentiality
Anonymity: researcher does not know who the subjects are (GOLD STANDARD)
Confidentiality: know information of subject but promise not to tell anyone. However, can be subpoenaed.
Deception and Misbehavior
allowed if it is minimal and if the participant knew it would affect the results.
have to identify you are a researcher
Humphrey Tearoom Trade
Watchman who observed homosexual sex in bathroom then follows them when they go back to their lives w/ their wives. Noted everything then showed up to the house asking health questions
IRB (review boards)
committees review research proposals (rights, welfare, and privacy, etc..)
Levels of IRB
Full: More than minimal risk, involves physical or emotional discomfort
Expedited: NOT greater than minimal risk: research with exhumed docs
Exempt: less than minimal risk ex: anonymous survey most popular *
expedited most common for CJ research
The enforcer (OHRP)
can shut down ALL research funding if ethical rules are broken
Epistemological Challenge
how do we know? how do we measure?
use statistics we cannot measure
Translating theory to number
we cannot attach a meter to a person. must build systematic bridges & empirical data points
Three - Step Roadmap
conceptualization, operationalization, and observation/measurement
Conceptualization
“Defining the THING”
taking an abstract term and addressing/agreeing on what is means for specific study
EX: “bullying” has to be clear on the definition of bullying. creates a shared target.
Direct Observations (Maxfield and Babbie Classification)
things we directly witness (window breaking)
Indirect observations (Maxfield and Babbie Classification)
hidden records needing proxy (logs)
Constructs (Maxfield and Babbie Classification)
theoretical deviation built from multiple compound observations (antisocial personality)
Operationalization
Writing the recipe
spelling out exact steps, procedures, and questions you will use to measure - 5 senses
ex: survey question “how do you feel” (safe, unsafe, very unsafe, somewhat safe, etc)
moving from definition to questions
2 Golden Rules (Exhaustive and Mutually exclusive categories)
Exhaustive: every possible case or respondent must fit into AT LEAST 1 visible category
ex: employed vs. unemployed (traps students, disabled, veterans, etc.)
Mutually Exclusive Categories: no respondent or case can fit in 2 categories
ex: overlapping age brackets (18-24 + 24-30) causes inaccurate data
NOIR Hierarchy - levels of measurement
Nominal - (names/labels) categories with zero math ranking. (political affiliation)
Ordinal - (rank/order) can be put in logical order, but distance is not math equal (strongly agree to strongly disagree) cannot know mathematically how much higher one is)
Interval - (Equals, Variables) equal distance between numbers but 0 does not mean “absolute” (temperature) RARE in basic CJ surveys
Ratio - (true 0 point) equal intervals and an absolute zero point where zero mean none of the variable exists. (# of prior arrests) THE GOLD STANDARD
Reliability vs. Validity
Consistency = reliability
Truth = validity
Bullseye Analogy
Reliability = the same every time
Validity = Accuracy
science in collaborative
perfect experiment has both reliability and validity
Classical Experiment
3 components
independent variable and dependent variable, pre-testing + post-testing, experimental and control group
Independent variable
the cause (policy/program)
have at least 1 in your study
ex: study time - when testing its effect on test scores
Dependent Variable
the effect (outcome)
all for explanatory research
ex: exam score - depending on study method
Pre-testing and post-testing
measuring the dependent variable before and after intervention
Experimental + control groups
groups that change vs. group that doesn’t
selected at random to ensure statistic equivalences at the start
example: one group get to study the other does not
Ethical Dilemmas
cannot random assign people to high-risk conditions (prison vs. freedom)
Retrospective Research
much of it look at crime after it happened. Makes clean “before and after” difficult
5 threats to internal validity
History - external event that influences outcomes (police brutality or current events)
Maturation - changes through passage of time and growth (aging out of crime or learning right from wrong)
Testing - pre-test effects responses to post-test (given the same test and scores better because they remember the answer)
Instrumentation - “ruler” could be affected by changes (changing from paper to digital system during an experiment)
Statistical Regression - High + Low extreme score will naturally move closer to average (extremely deviant naturally move to average)
Quasi-Experimental designs
used in CJ since we cannot randomize
Does not use all 3 parts of classical experiment
2 Major Types (Non-Equivalent-Groups Designs & Time-Series Design)
Non-Equivalent-Groups Designs - using a “comparison group” that is similar to experiment groups but not randomly assigned (inmates at 1 prison with education and one without)
Time-Series Design - examining a series of observations over time before and after interventions (a new DUI law)
both of these scientifically acceptable
What are surveys?
collecting data by asking questions through questionnaire can be multiple-choice, open-ended, or a combo of both
MOST FREQUENT TYPE of survey in CJ
Why surveys are used in CJ
Limit of official records: National Incident-Based Reporting System (NIBRS) data that tells us what has been reported or caught
Measure the Unobservable: allows to study; public attitudes to the police + courts, fear of crime and victim experience, self-reported offending + illegal drug use among juveniles + inmates.
National Crime Victimization Survey (NCVS)
is anonymous and tracks crime not reported
2/3 of crime not seen
Constructing: Operationalization + variables
turning abstract concepts into concrete survey items
ex: scale of how they treat the community fairly (concept: legitimacy)
rule of thumb: every questions must connect back to the core concept
Close-ended questions
mutually exclusive and exhaustive
multiple choice questions (1 answer)
benefit: quantitative coding + statistical analysis
Open-ended Questions
qualitative depth + answer in own words
conflict: different to code and quantify
Double - Barreled Question
two questions in one
fix: split the questions up
Biased or Leading Words
flaw: nudging the respondent (Don’t you agree)
fix: use neutral phrasing
Social Desirability Bias
respondents underreport illegal behaviors or unpopular attitudes to be socially acceptable.
Modes of Data Collection
1: Self-administered (web/mail) - Primary way pro: low costs, great for sensitive topics, convenient. cons: lower rates, risk of non-response bias
2: telephone service - pros: faster, moderate to high response rates. cons: mobile-only, caller ID screening
3: Face to Face interviews - pros: highest response, complex questions + observations. cons: expensive, high risk of interviewer bias
Problems of Non-response bias
non-response bias- are the people who responded only responding because they are extremely passionate about something where others did not care
mitigation strategies: follow ups, incentives, and demographic comparisons of your sample to the population
Logic of sampling
cannot study everyone, sampling selects a subset of population
Probability sampling
every unit has a known, non-0 chance of being selected GOLD STANDARD for reducing bias
(random, simple, stratified)
ex: picking numbers out of a hat
Non-Probability Sampling
used when sampling frame is not available
ex: snowball sampling for active drug dealers or hidden population
used in CJ research because we are finding the hard to find
Sampling Bias
systematic exclusion of certain members of the population. selection process favors some characteristics over others
Generalizability
ability to apply findings from sample to larger population
Case Study - Literary Digest
predicted president based on surveys of millions - 1936
reality: their prediction was wrong
why? the great depression, wealthy individuals favored rep. parts, poor people did not have the information they were using to give out this survey
Simple Random Sampling
pulling numbers out of a hat
Systematic Sampling
select every “nth” element from a list
ex: “every tenth”
Stratified Sampling
population divided in strata’s (groups) based on characteristic (race, gender) then random samples taken from each group
Cluster Sampling
used when full list of population not available, researchers sample groups first (police precincts) and sample individuals in those groups
Purposive Sampling
selects a sample based on own knowledge of the population and research aims (“gang leaders”)
Snowball sampling
method where existing people recruit future people from friends; essential for studying active use members.
GMM - things in beer
shows hypothesizing and predicting what will happen
GMM - lie-detector tests
if it violates the ethical guidelines (no harm, social/legal harm, voluntary and informed consent, anonymity vs confidentiality, and deception and misbehavior).
GMM - identifying brands
use of conceptualization, operationalization, and measurement
GMM - stuff in Hot Car
looks at independent variable, dependent variable, threats of internal validity, and control groups
