Question 2

Two Independent Groups In Kelley's (1950) classic study of the effects of people's expectations on their impressions of others, he gave Introductory Psychology students written descriptions of a guest lecturer before he came to class.Kelley handed out the descriptions at random.Half the students were told the visitor was a "warm" person and half were told he was "cold." After the visitor led a 20-minute class discussion, students rated the lecturer.Which design did Kelley use?

Accepted Answer

D) two matched groups 
A) experimental group-control group 
B) multiple independent groups 
C) two independent groups 
D) two matched groups
