correlations

Question 1

describe the A01 for correlations

Answer 1

-correlations are when you are looking for a relationship between 2 variables
-they use quantitative data of at least ordinal
-can use secondary or primary data
-there are no IVs or DVs just co -variables
-three types of correlation-positive, negative, no correlation
-correlation coefficients describe the strength of the correlation and is a measure from -1(strong negative) to 1(strong positive)

Question 2

what is a positive correlation

Answer 2

as one variable increases so does the other

Question 3

what is a negative correlation

Answer 3

as one variable increases the other decreases

Question 4

what are the strengths of using correlations

Answer 4

-they require little manipulation of behaviour so the data is already gathered making research quick/use existing data so quick easy
-can show unexpected correlation between two variables that was not previously thought of so new areas of research can be identified
-ethical as they can be used to research sensitive topics as no manipulation of variables is needed.

Question 5

what are the weaknesses of correlations

Answer 5

-cant assume cause and effect as just because there is a relationship doesnt mean there isnt other influencing variables
-dont account for EVs so not valid
-lack of correlation does not mean there is no relationship, correlations fail to account for non-linear relationships
