Question 1

correlation

Answer 1

a mathematical technique in which a researcher investigates an association between co-variables

Question 2

co-variables

Answer 2

the variables investigated within a correlation eg height and weight

they are not referred to as the independent and dependent variables because a correlation investigates association between variables rather than trying to show a cause and effect relationship

Question 3

correlation eval

Answer 3

• useful preliminary tool for research - strength and direction of relationship provides precise and quantifiable measure of how two variables are related
• starting points to assess possible patterns
• quick and economic as no need for controlled environment and no manipulation of variables
• secondary data can be used so less time-consuming
• tell us how but not why - lack of control
• cannot show cause and effect
• direction of effect is an issue
• intervening variables
• misused and misinterpreted
