Identify the type of this claim: A survey finds that clients with social anxiety spend an average of 4 hours per day avoiding social situations.

Frequency

100

The term is synonymous with consistency

Reliability

100

The extent to which a measure is subjectively considered a plausible operationalization of the conceptual variable in question.

Face Validity

100

The upward, downward, or neutral slope in a scatterplot denotes the ___ of the association.

Direction

100

This term describes a measure that gives inconsistent results, making it impossible to tell if it’s valid.

What is low reliability

200

Generalizability and representativeness of the sample are important to this validity.

External

200

The consistency in results every time a measure is used.

Test-Retest Reliability

200

The extent to which a measure captures all parts of a defined construct.

Content Validity

200

It denotes how closely the data points in a scatterplot cluster along a line of best fit drawn through them.

Strength (of slope)

200

Two therapists independently diagnose the same patient with PTSD after separate interviews. Their diagnoses show strong what?

Inter-rater reliability

300

Association claims can not control or manipulate variables and therefore it is not important to worry about this validity.

Internal

300

The degree to which two or more coders or observers give consistent ratings of a set of targets.

Interrater Reliability

300

The extent to which a measure is associated with a behavioral outcome with which it should be associated.

Criterion Validity

300

A single number, ranging from -1.0 to 1.0, that indicates the strength and direction of an association between two variables.

Pearson Correlation Coefficient (r)

300

A depression inventory gives the same score every time a client takes it, even though their mood is changing.

What is high reliability but low validity?

400

This validity is threatened when a researcher recruits participants who are easy to reach.

External

400

In a measure that contains several items, the consistency in a pattern of answers, no matter how a question is phrased.

Internal Reliability

400

The extent to which a self-report measure correlates with other measures of a theoretically similar construct.

Convergent Validity

400

A correlation-based statistic that measures a scale’s internal reliability.

Cronbach's Alpha (Coefficient Alpha)

400

If a personality test is supposed to measure impulsivity but instead captures anxiety, it’s lacking this type of validity.

Construct validity

500

Group A with participants aged (18-24) and Group B with participants (42-65) and the experiment is looking at how sleep affects decision making. Group A sleeps 7 hours and then preforms a task. Group B sleeps 2 hours and then preforms the same task. Group A preforms better than Group B. The experiment concludes that the less sleep an individual has the more poorly their decision making is affected. Discuss implications for Internal Validity.

This experiment has low or weak Internal Validity because age is a confound.

500

A ruler has high ______ reliability because it is consistent in its measurements of length.

Test-retest

500

The extent to which a self-report measure does not correlate strongly with measures of theoretically dissimilar constructs.

Discriminant (Divergent) Validity

500

A measure of internal reliability for a set of items, obtained by taking the mean of all possible correlations computed between each item and the others.

Average Inter-Item Correlation

500

A new “happiness” questionnaire has items that don’t seem related to each other and show little correlation with other measures of well-being. It lacks both of these measurement properties.
