Perfect positive linear correlation:
Correlation coefficient value is +1 then the two variables have perfect positive correlation.

Perfect negative linear correlation:
Correlation coefficient value is -1 then the two variables have perfect negative correlation.

Example of perfect positive linear correlation is: income and expenditure, heights and weights of a group of persons.

Example of perfect negative linear correlation: price and demand of a commodity, the volume and pressure of a perfect gas.

b. Critical values: r = ± 0.487 , no significant linear correlation
c. Critical values: r = ± 0.396 , significant linear correlation
d. Critical values: r = ± 0.487 , significant linear correlation
