The quiz about Chi-Square Association between attributes.

1. Two attributes $A$ and $B$ are said to be positively associated if

 
 
 
 

2. If for a contingency table, $df=12$ and the number of rows is 4 then the number of columns will be

 
 
 
 

3. The parameter of the Chi-Square distribution is ———–.

 
 
 
 

4. For $r\times c$ contingency table, the Chi-Square test has $df=$ ———-.

 
 
 
 

5. Two attributes $A$ and $B$ are said to be independent if

 
 
 
 

6. The presence of an attribute is denoted by

 
 
 
 

7. For the $3\times 3$ contingency table, the degrees of freedom is

 
 
 
 

8. The eye colour of 100 men is

 
 
 
 

9. There are ———– parameters of Chi-Square distribution.

 
 
 
 

10. The coefficient of association $Q$ lies between

 
 
 
 

11. A contingency table with $r$ rows and $c$ columns is called

 
 
 
 

12. If $\chi^2_c=5.8$ and $df=1$, we make the following decision ———-.

 
 
 
 

13. If $(AB) > \frac{(A)(B)}{n}$ then association is

 
 
 
 

14. The range of $\chi^2$ is

 
 
 
 

15. A characteristic which varies in quality from one individual to another is called

 
 
 
 

16. A $4 \times 5$ contingency table consists of ———.

 
 
 
 

17. If $(AB) < \frac{(A)(B)}{n}$ then association between two attributes $A$ and $B$ is

 
 
 
 

18. The value of $\chi^2$ cannot be ———.

 
 
 
 

19. Association measures the strength of the relationship between

 
 
 
 

20. The process of dividing the objects into two mutually exclusive classes is called

 
 
 
 

The relationship/ dependency between the attributes is called association and the measure of degrees of relationship between the attributes is called the coefficient of association. The Chi-Square Statistic is used to test the association between the attributes. The Chi-Square Association is defined as

$$\chi^2 = \sum \frac{(of_i – ef_i)^2}{ef_i}\sim \chi^2_{v},$$

where $v$ denotes the degrees of freedom

MCQs on Chi-Square Test quiz

A population can be divided into two or more mutually exclusive and exhaustive classes according to their characteristics. It is called dichotomy or twofold division if, it is divided into two mutually exclusive classes. A contingency table is a two-way table in which the data is classified according to two attributes, each having two or more levels. A measure of the degree of association between attributes expressed in a contingency table is known as the coefficient of contingency. Pearson’s mean square coefficient of contingency is

\[C=\sqrt{\frac{\chi^2}{n+\chi^2}}\]

Attributes are said to be independent if there is no association between them. Independence means the presence or absence of one attribute does not affect the other. The association is positive if the observed frequency of attributes is greater than the expected frequency and negative association or disassociation (negative association) is if the observed frequency is less than the expected frequency.
