The two attributes A and B are negatively associated if |
|
5 |
|
independent
positively associated
negatively associated
correlated
|
6 |
The sample size n is reasonably large so that for each cell, the estimated expected frequency must be at least |
2
3
4
5
|
7 |
When the expected frequencies are very small the value of=χ2has been |
adjusted
omitted
changed
all of these
|
8 |
If any ultimate class frequency is negative the data will be |
inconsistent
consistent
correlated
composite
|
9 |
The critical region of=χ2distribution is |
χ2 <χ2v; 1-α
χ2 <χ2v;1-α
χ2 <χ2 v;1-α/2
χ2 <χ2v;1-α/2
|
10 |
The value of coefficient of association lies between |
0 and + 1
-1 and + 1
-1 and 0
-0.5 and + 0.5

(AB), (Aβ), (αB), (αβ) are called |
positive class frequencies
negative class frequencies
natural class frequencies
ultimate class frequencies

The degree of relationship between the two attributes is called |
regressor
correlation
regressand
association
|
15 |
Degree of linear relationship between two variables is called |
regression
association
correlation
disassociation
|
16 |
A process of dividing the objects into two mutually exclusive classes of an attribute is called |
classification
trichotomy
dichotomy
association
|
17 |
A characteristic which varies in quality form one individual to another is called |
variable
constant
attribute
