Question 2

what is a single blind procedure

Answer 2

a procedure where participants are unaware of the experimental conditions they are operating under

Question 3

what is a double blind procedure

Answer 3

a procedure where both the participants and experimenters are unaware of the experimental conditions

Question 4

participant variables

Question 7

what is standardisation

Answer 7

procedures in research are all kept the same to increase replication and reliability

Question 8

Answer 8

situational variables

Question 9

what is counterbalancing

Answer 9

Question 10

Answer 10

participant sample divided in half, one half completes the two conditions in one order and the other half completes conditions in the reverse order
ABBA format
