correlations

Question 1

co-variables

Answer 1

the variables investigated within a correlation, for example height and weight

Question 2

positive correlation

Answer 2

as one co-variable increases so does the other

Question 3

negative correlation

Answer 3

as one co-variable increases the other decreases

Question 4

zero correlation

Answer 4

when there is no relationship between the co-variables

Question 5

correlations

Answer 5

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

Question 6

DIfference between experiments and correlations

Answer 6

Experiment → researcher controls/ manipulates IV to measure the effect on the DV

Correlations → NO manipulation of variable, not possible to establish cause and effect

Question 7

strengths of correlations

Answer 7

Preliminary tool for research
Precise and quantifiable measure
Starting point to assess possible patterns
Quick and economical to carry out

Question 8

limitations of correlations

Answer 8

Lack of experimental manipulation and control
Can’t say why variables are related
