WebKarl Pearson’s measure of association: To overcome from the drawback of χ2 association Karl Pearson defines another measure which is given by the formula: The value of this measure lies between 0 and 1. Higher value of the measure indicate the stronger association. The value 0 indicates that both the attributes are independent. Web2. If two attributes A and B are independent then the coefficient of association is equal 1. 3. A characteristic which varies in quality from one individual to another is called attribute. 4.
