Put them is ascending order. Count them = n. If n is odd, calculate (n+1)/2 the median is the value of the [(n+1)/2]th number in the ordered list. If n is even, the median is the average of the [n/2]th and [n/2 + 1]th numbers.

First arrange the data set in ascending order. Suppose the data set consists of n observations. the index for the lower quartile is (n + 1)/4 and the index for the upper quartile is 3*(n + 1)/4. Find the values that correspond to the number in these positions in the ordered list. For example, if n = 15, then lower index = 4 and upper index = 12. So the lower quartile is the fourth number and the upper quartile is the twelfth. If n is large, you may skip the +1 and just look at n/4 and 3n/4. Often the indices are not integers. Then, if you are a beginner (nd the fact that you asked this question suggests that you are), find the nearest whole numbers for the two indices. Otherwise you need to interpolate and that is a whole new ball game!

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.

disadvantages of index numbers

An index is a performance-tuning method of allowing faster retrieval of records. An index creates an entry for each value that appears in the indexed columns. By default, Oracle creates B-tree indexesThe syntax for creating a index is:CREATE [UNIQUE] INDEX index_nameON table_name (column1, column2, . column_n)[ COMPUTE STATISTICS ];UNIQUE indicates that the combination of values in the indexed columns must be unique.COMPUTE STATISTICS tells Oracle to collect statistics during the creation of the index. The statistics are then used by the optimizer to choose a "plan of execution" when SQL statements are executed.
