Research Methods 5n6 Correlations

Question 1

Research methods 5n6
Correlations
Are

Answer 1

Aims to discover association or relationship between 2 diff variables (co variables)

Question 2

Research methods 5n6
Correlations establish

Answer 2

Strength or type of relation

Question 3

Research methods 5n6
Positive corrolations

Answer 3

As one increases so does other
Or as one decreases so does other
Eg more hrs studied
Higher grade achieved

Question 4

Research methods 5n6
Negative corrolations

Answer 4

As one decreases other increases n vice versa
Eg more beers drank
Lower grade achieved

Question 5

Research methods 5n6
Zero corrolations

Answer 5

No relationship
Eg
Toe size and scores on a Test

Question 6

Research methods 5n6
What to include when asked to decsibe a scatter gram

Answer 6

If strong or weak
Type of corrolation
Pattern of variables eg longer treatment,lowered depression

Question 7

Research methods 5n6
Corrolation efficiency is what

Answer 7

Indicates direction n strength of relationship
Calc by statistical tests with ranges from 1to , -1
Perfect positive = 1
Perfect Negative =-1
No corro=0
A strong one eg is 0.6
A weak one is -0.6
Whichever number its nearest to either 1 0 or -1

Question 8

Research methods 5n6
Corrolations suggests trends

Answer 8

Which can lead to experiments when relations with 2 variables study then study can further knowledge of cause and effect

Question 9

Research methods 5n6
Useful when studies r unethical or impossible to conduct

Answer 9

Often the natural relationships studied would be unethical eg hrs spent in day care to level of aggression in child
So insight provided into inaccessible areas in psych
Also hard to dictate a behaviour in a study eg number of hrs slept.

Question 10

Research methods 5n6
High ecological val corrolations have

Answer 10

Cus naturally occurring variables

Question 11

Research methods 5n6
Limmit -not established cause n effect

Answer 11

Only measures degree of interrelationship between 2 variables
Cannot see If one causes other
May not be vaild

Question 12

Research methods 5n6
Different between experime t n corrolation

Answer 12

Experi- have IV N DV
established IV N DV
lab controls EVs so no confounding
Hypothesis states there will be difference in DV as result of IV
corrolations-two variables not IV OR DV
finding could be effected by EVs
States there will be relationship between 2 variables
