It may tell a different story than data collected by self-report questions

Martin has found a correlation of r = .18 between the two variables of using prescription stimulants (e.g., Adderall) and frontal lobe activity. This correlation is more likely to be statistically significant if: the study can be applied to the real world Martin used a larger number of subjects Martin's measure of prescription stimulant use is categorical Martin measured frontal lobe activity extremely accurately

Martin used a larger number of subjects

Which of the following is a unique threat to construct validity found only in behavioral observation? Yea-saying Observer bias Fence sitting Socially desirable responding

Observer bias

Validity

The ability of a test to measure what it is intended to measure

content validity

The degree to which the content of a test is representative of the domain it's supposed to cover.

While reading about a research study, which of the following would tell you that an association claim is being made? The presence of a scatterplot or bar graph The measurement of two variables The discussion of internal validity The use of a correlation coefficient

The measurement of two variables

A study finds a correlation coefficient of r = .52 and reports p < .05. The p value indicates which of the following? The effect size is large The null hypothesis (r = 0.00) is unlikely to be true for the sample The correlation is not statistically significant The correlation is negative

The null hypothesis (r = 0.00) is unlikely to be true for the sample

Two researchers tell you they study the same thing. However, when you look at their research papers, they do not use similar methodologies or measurements. How is this possible? The researchers have the same conceptual definitions (constructs) and operational definitions The researchers do not have the same conceptual definitions (constructs) nor the same operational definitions The researchers have the same operational definitions The researchers have the same conceptual definitions (constructs)

The researchers have the same conceptual definitions (constructs)

Which of the following is true of operational definitions? Conceptual definitions are created after operational definitions are determined. Operational definitions and conceptual definitions are the same thing. There is only one operational definition that is possible for each conceptual definition. The specification of operational definitions is one of the creative aspects of the research process.

The specification of operational definitions is one of the creative aspects of the research process.

Which of the following is NOT true of finding a stronger effect size in an association claim? There will be greater accuracy in predicting one variable from the other There will be greater likelihood of a finding being important in the real world There will be greater construct validity There will be a greater likelihood of finding a statistically significant relationship

There will be greater construct validity

Cronbach's alpha

a correlation-based statistic that measures a scale's internal reliability

known-groups paradigm

a method for establishing criterion validity, in which a researcher tests two or more groups, who are known to differ on the variable of interest, to ensure that they score differently on a measure of that variable

Likert Scale

a numerical scale used to assess people's attitudes; it includes a set of possible answers with labeled anchors on each extreme

directionality problem

a situation in which it is unclear which variable in an association came first

Supurious association

bivariate correlation is there but only because of the third variable

third variable problem

alternative explanation for association of 2 variables

ratio scale

numbers with equal intervals and 0 means none

correlation between two variables

effect size

describes the strength of an relationship between 2 or more variables

t-tests

difference between 2 means

internal reliability

different parts of the same test produce similar results

interval scale

equal intervals between levels and no true 0

restriction of range

full range isn't show making association seem smaller than it is

large

A question that leads people to answer in a particular way is known as a(n) negatively worded question double-barreled question ordered question leading question

leading question

Cirterion Validity

measure correlates with key behavioral outcome

Masked, or blind, study designs are designed to deal with bystander effect observer bias yea-saying biases faking good

observer bias

A study finds a correlation coefficient of r = .52 and reports p < .05. The p is a plausible significance approximation proportion assessment probability estimate population value

probability estimate

statistical significance

refers to the conclusion a researcher reaches regarding how likely it is they'd get a correlation of that size just by chance, assuming that there's no correlation in the real world

ordinal scale

represent ranked numbers

Observer bias relates mainly to ______, whereas observer effects stem from ______. outcomes; expectations researchers; participants validity; reliability faking good; faking bad

researchers; participants

Faking good is also known as socially desirable responding acquiescence nondifferentiation fence sitting

socially desirable responding
