2 multiple choice options
A _______________ measure operationalizes a variable by physiological; biological data
recording a participant's __________________. 3 multiple choice options
Test-retest reliability same test taker, same test, same scorer, done twice
2 multiple choice options
Interrater reliability same test taker, same test, different scorers
2 multiple choice options
Internal reliability same test taker, different test, same scorer
, A researcher asks in several different ways about how Internal Reliability
lonely you feel, and your responses are consistent with 2 multiple choice options
one another.
This is an example of ___________
Two observers measure how often a child smiles during Interrater Reliability
one hour at a daycare playground, and their counts are 2 multiple choice options
consistent with one another.
This is an example of __________ _.
Give an IQ test at Time 1, at the beginning of the Test-retest Reliability
semester, and again at Time 2, at the end of the 2 multiple choice options
semester. The scores should be relatively consistent
across the two times.
This is an example of __________ _.
A researcher finds that when 40 people take a five-item Internal Reliability
measure of extroversion, their answers to each of the 3 multiple choice options
five items are correlated. This is
Choose the correlation coefficient, r, with the strongest -.76
relationship. 3 multiple choice options
A professor gives a class a self-report measure of criterion validity
conscientiousness and finds that people who score 3 multiple choice options
high on the measure are more likely to be on time for
class. This is evidence for the measure's
If a scale or measure has good interrater reliability, it will have a positive slope on a scatterplot
3 multiple choice options
Which of the following correlations are the strongest? -.65
3 multiple choice options
1,283 adults with autism were observed in a social Criterion Validity
environment and completed my measure for adaptive 2 multiple choice options
behavior. The amount of adaptive behavior observed
was compared to my measure.
What kind of measurement system is this? physiological
"We measured levels of epinephrine and 3 multiple choice options
norepinephrine in plasma of mice 4 and 24 h after
photothrombotic stroke or sham surgery using a 2-
Catecholamine [Adrenaline-Noradrenaline] Research
ELISA kit (Rocky Mountain Diagnostics, Colorado
Springs, CO)" (Lechtenberg et al., 2019, 5)
What kind of measurement system is this? observational
"The participants were simply told to identify the target 3 multiple choice options
number "5" and were not told that there were different
presentation conditions." (Cohen & Quinlan, 2019, p.
1798)
