I have a doubt, like I know if we numerically code something like bad as 1 average as 2 and good as 3 then, it'll still be measured on ordinal scale but what if we do exactly opposite say, if I am saying that if a person's height is in between 2 feet to 4 feet he'll will be in category dwarf and if a person's height is from 5 feet to 7 feet he'll be in category tall then will it be measured on ordinal scale or on interval scale? and if it will be measured on interval scale then is it continuous or discrete?
SUPPORT TEAM PLEASE REPLY.

ACCORDING TO ME, IT WOULD STILL REMAIN AN ORDINAL SCALE OF MEASUREMENT . CONSIDER AN ANALOGY OF SAY RANKS GIVEN TO STUDENTS IN A CLASS. THE DIFFERENCE IN MARKS BETWEEN  THE  STUDENT WHO SECURED THE FIRST POSITION  AND THE ONE WHO STOOD SECOND MAY NOT BE THE SAME AS THAT OF BETWEEN THE SECOND AND THIRD. THEREFORE IT WOULD NOT BE UNWISE TO CONSIDER GRADES OR OTHER DATA WHEREIN WE GET SLABS( LABELS WITH RANGES) TO CONSIDER IT AS ORDINAL SCALE. 
IN PRACTICAL CASES , THE SLABS WE USE CANNOT BE DISCONTINUOUS. MOREOVER, SINCE IT IS AN ORDINAL SCALE, NO QUESTION ARISES OF WHETHER IT IS CONTINUOUS OR DISCRETE. THE QUESTION IS VALID IF IT IS NUMERICAL VARIABLE. 
HOPE IT HELPS!!
