CORRELATIONS FLASHCARDS
Cards in this deck (19)
- 1What is a correlation?A measure of the extent to which 2 variables are related
- 2What is correlational design?A way to test the relationship between 2 or more variables
- 3What are correlation co-efficients?Where the correlation is expressed numerically
- 4What can correlations not show?Cause & effect bc the IV isn't manipulated
Can only show a relationship - 5What is a positive correlation?When an increase in one variable tends to be associated w an increase w the other
- 6Give an exampleHeight & weight
- 7Positive co-efficient?0 - +1
- 8What is a negative correlation?When an increase in one variable tends to be associated w a decrease in the other
- 9Give an exampleHeight above sea level & temperature
- 10Negative coefficient?-1 - 0
- 11What is a zero correlation?When there is no relationship between 2 variables
- 12Give an exampleIQ & shoe size
- 13Zero coefficient?close to 0
- 14Give 2 strengths of correlations1. Can investigate unethical situations
2. Hardly any manipulation of behaviour - 15What does being able to investigate unethical situations mean?We can research subjects that wouldn't be possible to test in an experiment
e.g smoking & lung cancer - 16Why is there hardly an manipulation of behaviour?Bc the researcher only measures the variables doesn't manipulate
Therefore correlations have high ecological validity & mundane realism - 17Give a weakness of correlationsImpossible to prove cause & effect
- 18Why is this?There's no control over variables
Changes could be due to confounding variables - 19What does this mean?Correlations could lack internal validity & be open to manipulation
