Range

The range of r can be r<1 and r>1

The range of r can be r<1 and r>1
  1. Why does the r value range from 1 to 1?
  2. Can the coefficient of range be more than 1?
  3. What does it mean when r is +1?
  4. What is the range of a relation?

Why does the r value range from 1 to 1?

The correlation coefficient r ranges between -1 and +1. A positive r values indicates that as one variable increases so does the other, and an r of +1 indicates that knowing the value of one variable allows perfect prediction of the other.

Can the coefficient of range be more than 1?

Hence, its range lies between 0 and 1.

What does it mean when r is +1?

r = 0 means there is no correlation. r = 1 means there is perfect positive correlation. r = -1 means there is a perfect negative correlation.

What is the range of a relation?

The range of a function or relation is the set of all possible dependent values the relation can produce from the domain values. It is the collection of all possible outputs.
