Class Two Flashcards
what is reproducibility
ability to reproduce study results by other researchers
should the dependent variable be quantitative or qualitative
quantitative - numerical
why is it important for the control & experimental groups to be as similar as possible
to rule out confounding factors
placebo effect
believing that treatment is being administered which leads to a measurable effect
how to counter placebo effect
double blind experiment
what is sampling bias
if it is not equally likely for all members of a population to be sampled
what is attrition
participants dropping out of the study
construct validity
the instruments measure what they’re supposed to
replicability
repeated measurements lead to similar results
response bias
participants not having perfect insight into their state + providing inaccurate responses
between subjects design
comparisons made between subject (one group and another)
within subjects design
comparing the same group at different times
mixed methods research
combination of different research techniques
such as combination of between & within subjects design
type 2 error
concluding that there is no effect, false negative
type 1 error
saying there is an effect when there actually isn’t
is a type 1 or 2 error better
type 2 error
what is a p value
represents the probability that a difference observed is due to chance
a smaller p value means..
there is a stronger relationship
external validity
ability to apply scientific results to the real world
internal validity
are there inherent flaws in the design?
what are demand characteristics
the tendency of participants to act in ways that match how they are expected to behave
demand characteristics have an effect on..
internal validity
predictive validity
does the test tell us about the variable of interest?
impression management
participants adapting their responses to what they think the right response is
threat to internal validity
confounding variables
variables not accounted for that affects results
threat to internal validity
lack of reliability
measurement tools fo not measure what they should
threat to internal validity
sampling bias
e.g. selection criteria is not random
threat to internal validity
attrition effects
partipant fatigue
threat to internal validity
selection criteria
too restrictive criteria
threat to external validity
situational effects
presence of lab conditions changes outcome
threat to external validity
lack of statistical power
small groups have high variability
threat to external validity
why do ethical problems arise in experimental designs
researchers are manipulating variables - not just observing in nature
pros and cons of non-experimental designs
pro: observing results in a natural setting
con: reduced control of variables - reduced internal validity
correlational studies
looks at the relationship between 2 quantitative variables
ethnographic studies
qualitative method where researchers immerse themselves in the culture of the people they are studying
greatest strength of ethnographic studies
depth of analysis
cons of ethnographic studies
usually working alone: no critique of methodology
presence of researcher: affects the group’s behaviours
objectivity of the researchers is threatened (attachment with culture)
twin studies
test the relationship between nature and nuture
best way to test heritability
twin studies
what is heritability
the extent to which an observed trait is due to genetics vs environment
longitudinal studies
how individuals develop over time along a research variable
disposition at birth effecting the life we live
pros and cons of longitudinal studies
pro: looking at how a factor can develop over time
cons: high attrition rates, costly + need lots of resources
cross sectional study
data collection of a population at a specific time
case studies
in depth exploration of one individual/case
phenomenological studies
attempts to understand people’s perceptions/perspectives
usually by researchers studying themselves
phenomenological studies
attempts to understand people’s perceptions/perspectives
usually by researchers studying themselves
pros and cons of phenomenological studies
pro: detail + in depth understanding
con: can’t generalize + small sample size (reduced external validity)
pros and cons of surveys
pro: easy to administer & cost effective
con: participants don’t feel encouraged to give honest answers & poor questions
archival studies
analyze already collected data from historical records
biographical studies
accounts of an individual’s life experiences
functions of family (5)
reproduction
protection
socialization (passed down norms)
affection + companionship
social status (family background)
nuclear family
direct blood relations
extended family
grandparents, aunts, uncles etc.
monogamy
form of marriage - 2 individuals
polygamy
multiple wives/husbands
polygyny vs polyandry
polygyny: one man & 2+ women
polyandry: one woman & 2+ men
endogamy
marrying within a certain group
exogamy
marrying outside of a certain group
(prohibition of sexual relationships between relatives)
what is bilateral descent
kin groups involving both maternal & paternal relations
patriarchy
men having more authority than women
egalitarian family
spouses treated as equals
4 types of child abuse
physical, emotional, sexual and neglect
abuse has been linked to..
alcohol consumption, mental illness & certain social conditions
manifest functions of education
pass down knowledge + give status to educated people
latent functions of education
socialization + maintaining social control
hidden curriculum of schools
often conflicts with the manifest curriculum
educational segregation
widening disparity between children from high-income areas and those from low-income areas
teacher expectancy theory
teachers form expectations of students + act towards students in this manner
student will perform in accordance if they decide the expectations are reasonable
ecclesia
dominant religious organization that includes most members of society - official religion + doesn’t tolerate others
church
a religious organization that is well integrated into larger society
allows people to join
sect
a religious organization that is distinct from society - often formed by breaking away from a larger religion
e.g. Mormons
cult / new religious movement
far outside society’s norms & involves a very different lifestyle
