25
case study, observational study, qualitative study and surveys are all examples of what?
descriptive studies
26
define what a correlational study is
finding whether there is a large relationship, very little relationship or no relationship between two variables
27
define what an experiment is
manipulating one thing to see if it changes another thing
28
manipulating one thing to see if it changes another thing is called what?
an experiment
29
finding whether there is a large relationship, very little relationship or no relationship between two variables is referred to as what kind of study?
correlational
30
what is a descriptive method in psychology?
a way for researchers to understand behaviour without manipulating variables or establishing cause and effect relationships **focuses on observing, recording and analyzing things as they naturally occur
31
define case study
focuses in depth and gives a lot of details regarding a person or small group of people
32
where is a case study a good method of research to use?
-studying rare cases -when you want a lot of detailed info -insight into unethical circumstances -gives clinical insight -good choice for studying over long periods of time
33
where is a case study a weak method of research to use
-cannot be generalized as everyone and every situation is different -risk of observer bias (interpreting data subjectively) -can take a lot of time to gather information -don't establish cause/effect relationships
34
what is an observational study?
watching and recording behaviours without trying to change or influence them; the goal is to understand how things naturally occur
35
define naturalistic observation
real world settings, high chance of validity as it is in a natural environment; some researchers try to prevent being observed themselves in their studies
36
define laboratory observation
more control over the environment, participants are not necessarily always aware they are being observed, may be some interference
37
what are some strengths of observational studies?
-provide insights into behaviours in natural settings (more applicable to everyday life) -they can be adapted to any environment and population -more accurate than self reporting studies
38
what are some weaknesses of observational studies?
-no determination of causality -observer bias (influenced interpretations) -little control of study environment
39
define psychological testing
measure and evaluate mental function and behaviors like intelligence, aptitude, abilities and personality
40
what are the two types of psychological testing?
objective and projective
41
define objective psychological testing
measures beliefs or feelings within conscious awareness
42
define projective psychological testing
reveals unconscious feelings or motives
43
what is an example of a projective psychological test?
asking participants to interpret an inkblot stain- what do you see?
44
what is a thematic apperception test?
people are shown ambiguous scenes and asked to create a story based on their perception
45
what can a thematic apperception test be used for?
describe aspects of emotional disturbance in children
46
what is significant about a TAT?
people project their own beliefs and experiences onto what they see in the study
47
what are some key differences between a psychological test versus a survey?
-psychological measures specific things, survey is more broad -psychological is more standardized, surveys vary in design -psychological can include subjective or objective questions, surveys primarily use self report
48
what are the strengths of surveys?
-large samples -cost effective -standardized -quick and easy -quantitative and qualitative data
49
what are the weaknesses of surveys?
-people may not necessarily answer truthfully -questions can be misunderstood -limited depth -experimenter lead
50
define mode
the value that occurs the most frequently in a set of data
51
define dispersion
how closely packed or spread out around the central tendency
52
what is the simplest measure in data?
range: distance between the greatest and lowest score
53
what is the most common measure?
stand deviation: dispersion of data relative to the mean and is the square root of the variance
54
define qualitative inquiry
using non numerical data (stories, film, news) to uncover deeper understanding of human experiences and interactions
55
what is significant about qualitative inquiry?
makes no claim to objectivity or replicability
56
define ethnography
immersing yourself in a group or environment to understand culture
57
define pos correlation
both variables depend on each other, if one is high the other is also high and vice versa
58
define neg correlation
one variable is higher than the other
59
coefficient of correlation
between -1.00 and 1.00; when identifying strength ignore the signs, whatever number is biggest is the strongest correlation
60
define linear relationship
when variables on a scatterplot can be easily fit on a line
61
what do correlations tell us? what do they not tell us?
tell us how two variables are related, they cannot tell us anything about causality
62
define spurious relationship
relationships between variables in which a causal variable explains the relationship
63
what is a strength of correlations?
you can make general predictions about the variables
64
what does it mean for a hypothesis to be directional?
proposes a cause and effect relationship
65
define control condition
participants are not exposed to the same treatment as in the experimental condition **used for comparison**
66
define experimental condition
exposure to manipulation of the independent variable
67
define meta analysis
when you combine and statistically analyze the results of many studies
68
what is the best way to avoid assignment issues in research?
random assignment
69
define confounds
factors other than the independent variable that may be responsible for differences in the dependent variable
70
how do researchers manage subject expectancy?
single blind study- participants do not know if they are the control or experimental group
71
how do researchers manage experimenter expectancy?
double blind study- no one knows who is assigned as the control or experimental group
72
define a significance test
likelihood your results are due to chance and not your manipulation of the variables
73
define internal validity
you feel confident about the causal statements which happened in the study
74
define external validity
you feel confident you can generalize your results to people outside of your study
75
define deception
when participants are not completely informed about the nature of the research before agreeing to do it *used when necessary
76
define active deception
intentionally misleading; used when knowing the purpose of the study might affect the behaviour or results
77
define passive deception
withholding information but not actively providing false information; used when full disclosure may impact results but there is no need to mislead people
