Q

populations

Study These Flashcards
A

the overall group of individuals that the researchers are interested in

24
Q

mode

Study These Flashcards
A

most frequently occurring response

25
median
lies at the middle of a data set
26
mean
arithmetic average of all data points (most useful)
27
archival research
using records and parts research to look for interesting patterns or relationships
28
longitudinal research
research design in which data-gathering is administered repeatedly over an extended period of time (same groups of people over time)
29
cross-sectional research
the research compares multiple segments of the population at the same time (different generations of people)
30
attrition
reduction in the number of research participants due to dropouts
31
correlation
there is a relationship between two or more variables, but this relationship does not necessarily imply cause and effect
32
correlation coefficient
a number from -1 to +1 that indicates the strength and direction of the relationship between variables (represented by the letter r)
33
positive correlation
the variables move in the same direction
34
negative correlation
the variables move in opposite directions
35
confounding variable
actually causing the systemic movement in our variables of intrest
36
illusory correlations
false correlations, occur when people believe that relationships exist between 2 things when no such relation exists
37
confirmation bias
looks for evidence to support a hunch, while ignoring evidence that tells the hunch is false
38
operational definition
a precise description of out variables and it is important in allowing others to understand exactly how and what a researcher measures in a particular experiment
39
experimenter bias
the possibility that a researcher's expectations might skew the results of the study
40
single-blind study
one of the groups (participants) is unaware as to which group they are in (experimental or control) while the researcher who developed the experiment knows which participants are in each group
41
double-blind study
both researchers and participants are blind to group assignments
42
placebo effect
occurs when people's expectations influence their experience in a given situation
43
independent variable
manipulated or controlled by the experimenter
44
dependant variable
measurement of effect the independent variable had
45
participants
subjects of psychological research that actively participate in the process
46
random sample
subset of a larger population in which every member of the population has an equal chance of being selected
47
random assignment
all participants have equal chance of being assigned to either group
48
statistical analysis
determines how likely any difference found is due to chance
49
peer-reviewed journal articles
aimed at an audience of professionals and scholars who are actively involved in research themselves
50
replicate
repeat the experiment using different samples to determine reliability
51
reliability
the ability to consistently produce a given result
52
validity
the extent to which a given instrument or tool accurately measures what it's supposed to measure
53
institutional review board (IRB)
committee of individuals often made up of members of the institution's administration, scientists and community members
54
informed consent
provides a written description of what participants can expect during the experiment, including potential risks and implications of the research
55
deception
purposely misleading experiment participants in order to maintain the integrity of the experiment, never to the point of harmfulness
56
debriefing
complete, honest information about the purpose of the experiment, how te data will be used, why deception was necessary, how to obtain more information about the study
57
institutional animal care and use committee (IACUC)
institutional administrators, scientists, veterinarians and community members
