ideally, an index should possess the following properties:clarity, simplicity and objectivity:-the index should be easy to apply so that there is no undue time lost during field examination. the criteria of the index should be clear and unambiguous.validity:- it must measure what it is intended to measure, so it should correspond to clinical stages of the disease under study at each pointreliability:- the index should measure consistently at different times and a variety of conditions. the ability of the same or different to interpret and use the index in the same wayquantifiability:- it should be responsive to the statistical analysis so that the status can be expressed by a number that corresponds to a relative position on a scale of 0 to the upper limitsensitivity:- should be able to detect reasonably small shifts in either direction in the group or individual conditions.acceptability:- the use od index should not be painful or demeaning to the subject.

Dense Index: An index record appears for every search key value in file. This record contains search key value and a pointer to the actual record. Sparse Index: Index records are created only for some of the records. To locate a record, we find the index record with the largest search key value less than or equal to the search key value we are looking for. We start at that record pointed to by the index record, and proceed along the pointers in the file (that is, sequentially) until we find the desired record. - - (ref: http://sawaal.ibibo.com/computers-and-technology/difference-between-sparce-index-dence-index-773764.html)

According to Prof.Fisher "the formula for calculating an index number should be such that it gives the same ratio between one point of comparison and the other no matter which of the two is taken as the base" ie, P01 * P10 = 1
A= 4 times the base of square mass
