The value of the correlation coefficient r lies between
(a) 0 and 1 (b) minus one and plus one (c) minus infinity and plus infinity (d) 0 and 100
Answer: (b) minus one and plus one - a value outside this range signals an error.
The unit of the correlation coefficient between height in feet and weight in kg is
(a) kg/feet (b) percentage (c) non-existent (d) feet
Answer: (c) non-existent - r is a pure number with no unit.
If r is positive then the two variables
(a) move oppositely (b) move in the same direction (c) do not change (d) are equal
Answer: (b) move in the same direction - the sign shows direction.
Which method suits data that can only be ranked?
(a) Pearson (b) Spearman rank (c) mean (d) mode
Answer: (b) Spearman rank - it works on ranks, not measured values.
A correlation of zero means
(a) perfect link (b) no linear link (c) negative link (d) cause and effect
Answer: (b) no linear link - a curved relation may still exist.
