Question

When the value of the independent variable increases and the value of the dependent variable
Increases such type of correlation is

  1. positive correlation
  2. negative correlation
  3. no correlation
  4. constant correlation

hintHint:

Correct option is (d).
With increase in independent variable if there is increase in dependent variable , the correlation is positive . The garph will be upward and the slope will be positive

The correct answer is: positive correlation


    When the value of the independent variable increases, and the value of the dependent variable is called a positive correlation.

    The scatter plot shows David’s height at various ages. Choose the right answer that describe the type of association between David’s age and his height.

    The corerect option is (c)
    Reason :
    As the height of David increases with increase in his age , the graph is going upward as both the variable are increasing so it is a case of positive association and since there is almost constant change in both the variable it is shows linear relationship also
