Q

Essential Components of science: Skepticism

A

testable, data can be replicated and peer-reviewed (don’t trust if study says it’s correct, must go through a process)

Q

Theory: must be 3 things

A
  • testable (leads to hypo)(try to falsify hypo)
  • parsimonious (few variables, constructs)
  • consistent

Q

The role of theories: steps (3)

A

Q

The role of theories: if predictions are CONFIRMED

Q

The role of theories: if predictions are DISCONFIRMED

Q

Experimental Realism:

A

participants are psychologically engaged (increases internal validity)

25
Mundane realism:
looks like real life (field study) | -can lose control resulting in low internal validity but his external validity
26
Correlational studies (2)
- relationship btw two variables | - lack of causation
27
Correlational problems (2)
- bi-directionality | - 3rd variable (confounds)
28
Self report challenges
- may lie | - may not know something about themselves
29
Survey challenges
- social desirability | - they way you word surveys could impact responses
30
observation (ways)
videotape | observe people
31
Archival research (def)
getting data from surveys that have already been conducted.
32
Two types of measurment:
reliability | validity
33
Reliability
repeatability
34
validity
am I measuring what I intend to measure
35
can't have_____w/o___
validity w/o reliability
36
Measurement error
not all doing it the same way
37
which one is the min requirement
reliability
38
types of sample (2)
probability | non-probability
39
probability- types
we know the prob of being selected - random sample (most basic) - stratified
40
random sample
equal chance of being selected out of pop for sample
41
stratified
create more representation (see baseball image) going from a pop to a sample
42
non-probability-type
I don't know the probability | convenience
43
convenience- why is the most common one?
select people who meet basic criteria | -easiest one
44
descriptive stats
describes our sample
45
frequency
how often an event occurs
46
central tendency: 3
Mean: avg mode: most common score median: middle number
47
when are mean and median preferred?
mean is preferred because it includes all scores but when the distribution is skewed use the median because CEO pulls the mean number making it seem larger!
48
STD
how wide apart or how compressed scores are
49
inferential stats
test hypos, allows us to make inferences from sample to population
50
types of statistical analyses
t-test: comparing 2 groups Anova: analysis of variance, used when 3 or more conditions correlation: rs btw 2 variables -----regression: quality of rs(2/more variables)
51
Bias
can be participant or experienter
52
participant: social desirabilty
they present themselves in a socially desirable way
52
participant: social desirabilty
53
how to detect social D
- word surveys to see if doing it (always, never) | - word questions differently to see if consistent
54
experimenter bias
might behave in ways that indicate participants how they should act
55
how to avoid experimenter bias
standerizarion (scripts, automate, double-blind)
56
informed consent
partip should be volunteers so have to give enough info for them to want to participate; dont have to tell hypo.
57
two ways to debrief
de-hoax: explaining hypo | desensitize: removing any negativity if done to them
58
IRB what are three things you have to present to IRB when using deception
- use least amount of it - tell partip about deception - need deception for study to work
