Qualitative data can be classified into three groups:
1. Binary Data:
If any quality is measured in terms of its presence or absence
then it is termed as Binary data. In other words if an attribute
posses only two category then it is called as Binary data.
2. Nominal Data:
If an attribute posses more than two categories which cannot be
arranged in any order then it is termed as Nominal data.
3. Ordinal Data:
If an attribute posses more than two categories which can be
arranged in ascending/descending order then it is termed as
Ordinal data.

With 3 points we can describe a polynomial of degree 2 .
so our desired polynomial is of the form y=ax2 + bx + c.
plugging the above given values in the above quadratic equation we get
5 = a x 0 + b x 0 + c
=> c = 5.
6 = a x 1 x 1 + b x 1 +c
=> 6 = a+ b + c
but c = 5
so a + b = 1
also
8 = a x 2 x 2 + b x 2 +c
8 = 4a + 2b + 5
but a+b = 1 using this we get
b = 1/2 , a = 1/2, also c = 5
using these values we get value for P(3) as:
(1/2) x 3 x 3 + (1/2) x 3 +5
9/2 + 3/2 +5 = 1

The ordinal scale places events in order, but there is no attempt to make the intervals of the scale equal in terms of some rule. Rank orders represent ordinal scales and are frequently used in research relating to qualitative phenomena. A student`s rank in his graduation class involves the use of an ordinal scale. One has to be very careful in making statement about scores based on ordinal scales.
