24
Q

Strong/Weak are examples of what?

A

the strength of the correlation

25
Q

What is meant by the strength of a correlation?

A

how close each plot is to each other and the line

26
Q

What is meant by the direction of a correlation?

A

the direction the plots point to on a scattergraph

27
Q

Interpret a strong correlation

A

all the points on a scattergraph are close to the line/close together

28
Q

What is meant by a strong correlation?

A

all the points on a scattergraph are close to the line/close together

29
Q

Describe a strong correlation

A

all the points on a scattergraph are close to the line/close together

30
Q

Interpret a weak correlation

A

33
Q

Exam tip: what must you comment on when asked to interpret a correlation?

A

the strength AND the direction

34
Q

What is meant by a correlation co-efficient?

A

it is the result from a correlation statistical test (numerical version of a correlation)
