children in their classrooms who have attention-deficit/hyperactivity disorder
(ADHD). He will evaluate how positively or negatively the children are treated by

Naomi is studying the effect of popularity on academic success for her research

popular each member of their class is. She then uses this information to rank the

Dr. Sheffield is a clinical psychologist who specializes in treating pathological
gambling. Pathological gambling is defined as being unable to resist impulses to
gamble. Bothered by not having a good measure that he can give to clients to
determine whether they are suffering from this condition, he creates a new
measure of pathological gambling. The measure has 15 questions, and it takes 20
minutes to complete. Dr. Sheffield gives his measure to his supervisor, who is also
an expert in pathological gambling. His supervisor says that his measure appears
to test all the components of pathological gambling, including feeling restless
when attempting to stop gambling, jeopardizing jobs in order to keep gambling,
and using gambling to escape from problems and a bad mood. Given this
information, Dr. Sheffield's measure has evidence of which of the following? -

the same videos periodically. Which type of reliability is Dr. Leising calculating? -

between two measurements
"A strong relationship was found. Children with more positive relationships with

Another word for discriminant validity is ______ validity - ✔✔divergent
In order to use the known groups paradigm to establish criterion validity, which of
the following is necessary? - ✔✔After testing, the groups should have significantly
different scores on the measure
Which of the following is an example of physiological measurement? -
✔✔measurements of hormones in the bloodstream
