Psych 206 Quiz #3

when people are using an acquiescent response set they are:

tending to agree with every item, no matter what it says

internal reliability, interrater reliability, or test-retest reliability? a researcher finds that people's scores on a measure of extroversion stay stable over 2 months

test-retest reliability

what is a way of preventing reactivity?

waiting for the participants to become used to the observer

what situation do people most accurately answer survey questions?

when they are describing their subjective experience; how they personally feel about something

"is your cell phone new and does it have all the latest features?" what is the biggest problem with this wording?

it is a double-barreled question

what makes it more likely that behavioral observations will have good interrater reliability?

a clear codebook

face validity, content validity, convergent and discriminant validity, or criterion validity?The researcher e-mails his five-item measure of conscientiousness (e.g., "I get chores done right away," "I follow a schedule," "I do not make a mess of things") to 20 experts in a personality psychology, and asks them if they think his items are a good measure of conscientiousness.

face validity

ordinal, ratio, interval? a students grade in school

interval

face validity, content validity, convergent and discriminant validity, or criterion validity?The researcher e-mails his five-item measure of conscientiousness (e.g., "I get chores done right away," "I follow a schedule," "I do not make a mess of things") to 20 experts in a personality psychology, and asks them if they think he has included all the important aspects of conscientiousness.

content validity

face validity, content validity, convergent and discriminant validity, or criterion validity?A professor gives a class of 40 people his five-item measure of conscientiousness (e.g., "I get chores done right away," "I follow a schedule," "I do not make a mess of things"). Average scores are more highly correlated with a self-report measure of tidiness (r=.50) than with a measure of general knowledge (r=.09).

convergent and discriminant validity

face validity, content validity, convergent and discriminant validity, or criterion validity? A professor gives a class of 40 people his five-item measure of conscientiousness (e.g., "I get chores done right away," "I follow a schedule," "I do not make a mess of things"). Average scores are correlated (r=-.20) with how many times each student has been late to class during the semester.

criterion validity

internal reliability, interrater reliability, or test-retest reliability? a researcher asks a sample of 40 people a set of five items that are all capturing how extroverted they are. The Cronbach's alpha for the five items is found to be .65.

internal reliability

internal reliability, interrater reliability, or test-retest reliability? an infancy researcher wants to measure how long a 3-month-old baby looks at a stimulus on the right and left sides of a screen. Two undergraduates watch a tape of the eye movements of ten infants and time how long each baby looks to the right and to the left. The two sets of timing are correlated r=.95.

interrater reliability

what is a means of controlling for observer bias?

making sure the observer does not know the study's hypothesis

ordinal, ratio, interval? a books sales rank on amazon

ordinal

Which correlation coefficients best describes the pictured scatterplot?

r=-.95

ordinal, ratio, interval? Degree of pupil dilation in a person's eyes in a study of romantic couples (measured in millimeters)

ratio

ordinal, ratio, interval? number of books a person owns

ratio
