Question 2

Answer 2

consistency

Question 3

types of reliability

Answer 3

Question 4

Answer 9

test-retest

Question 10

test-retest reliability

Answer 10

doing the same test on the same Ps on 2 seperate occasions and comparing results to see if they are similiar - high-correlation=high test-retest reliability

Question 11

how to improve reliability
