Q

Strong/Weak are examples of what?

A

the strength of the correlation

25
What is meant by **the strength** of a correlation?
how close each plot is to each other and the line
26
What is meant by the direction of a correlation?
the direction the plots point to on a scattergraph
27
Interpret a strong correlation
all the points on a scattergraph are close to the line/close together
28
What is meant by a strong correlation?
all the points on a scattergraph are close to the line/close together
29
Describe a strong correlation
all the points on a scattergraph are close to the line/close together
30
Interpret a weak correlation
all the points on a scattergraph are spread far apart and away from the line
31
What is meant by a weak correlation?
all the points on a scattergraph are spread far apart and away from the line
32
Describe a weak correlation
all the points on a scattergraph are spread far apart and away from the line
33
Exam tip: what must you comment on when asked to interpret a correlation?
the strength AND the direction
34
What is meant by a correlation co-efficient?
it is the result from a correlation statistical test (numerical version of a correlation)
35
What do we call the result of a correlation statistical test?
correlation Co-effiecient
36
What does a correlation co-efficient show?
the strength of a correlation (strong/weak)
37
What does a correlation co-efficient of -1 show?
Strong negative correlation
38
What does a correlation co-efficient of +1 show?
Strong Positive correlation
39
When writing a correlational what things must we include?
Relationship/Link Co variables
40
What is the main criticism of a correlation?
can not establish cause and effect
