Scatter Plot

Q

Correlation Coefficient

A

a number between -1 and +1 that reflects the degree to which one variable, traditionally called y, is a linear function of another, traditionally called x

a negative correlation means that as x goes up, y goes down

a positive correlation means that as x foes up, so does y

a zero correlation means that x and y are unrelated

Q

Objective Test

A

a personality test that consists of a list of questions to be answered by the subject as true or false, yes or no, or along a numeric scale

30
Q

Factor Analysis

A

a statistical technique for finding clusters of related traits, tests, or items

31
Q

p-Level

A

in statistical data analysis, the probability that the obtained correlation or difference between experimental conditions would be expected by chance

32
Q

Type I Error

A

in research, the mistake of thinking that one variable has an effect on, or relationship with, another variable, when it really does not

33
Q

Type II Error

A

in research, the mistake of thinking that one variable does not have an effect on or relationship with another, when it really does

34
Q

Effect Size

A

a number that reflects the degree to which one variable affects, or is related to, another variable

35
Q

Binomial Effect Size Display (BESD)

A

a method for displaying and understanding more clearly the magnitude of an effect reported as a correlation, by translating the value of r into a 2x2 table comparing predicted with obtained results

36
Q

Replication

A

doing a study again to see if the results hold up

replications are especially persuasive when done by different researchers in different labs than the original study

37
Q

Publication

A

the tendency of scientific journals preferentially to publish studies with strong results

38
Q

Questionable Research Practices (QRP’s)

A

research practices that, while not exactly deceptive, can increase the chances of obtaining the result the researcher desires

39
Q

p-Hacking

A

analyzing data in various ways until one finds the desired results

40
Q

Open Science

A

a set of emerging principles intended to improve the transparency of scientific research and that encourage fully reporting all methods and variables used in a study, reporting studies that failed as well as succeeded and sharing data among scientists

41
Q

What is Funder’s Second Law?

A

there are no perfect indicators of personality; there are only clues, and clues are always ambiguous

the clues may be wrong

42
Q

What is Funder’s Third Law?

A

something beats nothing, two times out of three

need evidence, not just a gut feeling

43
Q

What are the advantages of S-Data?

A

high face validity
large amount of data
access to thoughts, feelings, and intentions
definitional truth: self judgements are the only trustworthy truth of things such as self-worth
causal force
simple and easy

44
Q

What are the disadvantages of S-Data?

A

bias
error
too simple and easy (overuse)

45
Q

What is face validity?

A

the degree to which an assessment instrument appears to measure what it is intended to measure

46
Q

What factors reduce reliability?

A

random variation or mistakes, result in measurement error

47
Q

What factors reduce validity?

A

directed, pointing to one particular result, results in bias

48
Q

What are the advantages of I-Data?

A

real-world bias
large amount of data
common sense
definitional truth
causal force

49
Q

What are the disadvantages of I-Data?

A

limited information
lack of access to private experience
bias
error

50
Q

What are the advantages of L-Data?

A

not prone to bias
intrinsic importance
psychological relevance

51
Q

What are the disadvantages of L-Data?

A

multi-determinism: somethings are determined by multiple things not just personality
may lack relevance or be hard to access
records may be incomplete or inaccurate

52
Q

What are the advantages of B-Data?

A

wide range of contexts
appearance of subjectivity

53
Q

What are the disadvantages of B-Data?

A

difficult and expensive
uncertain interpretation

54
Q

How is S data differentiated from B data?

A

S data: asking people about themselves
B data: performance based assessments, people demonstrate behaviors, not report them

55
Q

What is reliability?

A

consistency in measurement

56
Q

What is test-retest reliability?

A

consistency over time

only for traits, not for states

57
Q

What is inter-rater reliability?

A

consistency among observers

58
Q

What is internal consistency?

A

consistency across items all measuring the same thing

59
Q

What is validity?

A

the degree to which a measurement actually measures what is it supposed to

60
Q

What is construct validity?

A

establish that our measure is related to the construct we want to measure

61
Q

What is criterion validity?

A

outcome or behavior

62
Q

What is convergent validity?

A

someone should score high on extraversion and low on introversion

63
Q

What is discriminant validity?

A

make sure we are measuring intelligence, not just how much the child talks

64
Q

What is Funder’s Fourth Law?

A

there are only two kinds of data; terrible data and no data

the potential shortcomings of all kinds of data are precisely what require researchers to always gather every kind they possibly can

65
Q

What are the four conditions of rational test construction?

A

items mean the same thing to the test taker and creator

capability for accurate self-assessment

willingness to make an accurate and undistorted report

items must be valid indicators of what is being measured

66
Q

What are experimental methods?

A

manipulated at least one variable

can demonstrate causality

determine whether one variable can affect another

not possible (or ethical) with certain variables

67
Q

What are correlational methods?

A

measured variables

can’t demonstrate causality

shows how often or how much variables are related, typically

68
Q

What is a representative design?

A

generalizability across people
generalizability across methods/designs
consistency in patterns

69
Q

What is the p level?

A

the probability that the obtained correlation or difference between conditions would be expected by chance

the probability of getting the result found, if the null hypothesis were true

70
Q

What are the problems with significance testing?

A

the logic is difficult to describe (and understand)

the criterion for significance is a arbitrary rule of thumb

nonsignificant results are sometimes misinterpreted to mean “no result” or no relationship or difference

only provides information about the probability of one type of error

71
Q

What is the effect size?

A

strength of association

more meaningful than a significance (p) level

many effect-size measures have been developed

correlation coefficient or Cohen’s d

can be used for predictions

72
Q

How can we make research more dependable?

A

use larger numbers of participants

disclose all methods

share data

report studies that don’t “work”, and explore your data

never regard one study as conclusive proof of anything
