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.

Value weighted index is a market average such as Standard & Poor's 500 Index that takes into account the market value of each security rather than calculating a straight price average. An equal weighted index is a type of weighting that gives the same weight, or importance, to each stock in a portfolio or index fund. The difference is one gives individual value and other gives one value to all.

Unless you have a keen and educated eye, telling the difference between them is difficult.
the contour interval is the difference in elevation between contour lines that are next to each other
an index shows where a certain word or phrase is in a book, the glossary tells the definition of words in a book.
