2. doubt that you have to sort the data. use the quartile function to do it. From the help file:

QUARTILE

Returns the quartile of a data set. Quartiles often are used in sales and survey data to divide populations into groups. For example, you can use QUARTILE to find the top 25 percent of incomes in a population.

Syntax

QUARTILE(array,quart)

Array is the array or cell range of numeric values for which you want the quartile value.

Quart indicates which value to return.

If quart equals QUARTILE returns
0 Minimum value
1 First quartile (25th percentile)
2 Median value (50th percentile)
3 Third quartile (75th percentile)
4 Maximum value

Remarks

If array is empty or contains more than 8,191 data points, QUARTILE returns the #NUM! error value.

If quart is not an integer, it is truncated.

If quart < 0 or if quart > 4, QUARTILE returns the #NUM! error value.

MIN, MEDIAN, and MAX return the same value as QUARTILE when quart is equal to 0 (zero), 2, and 4, respectively.

Example

QUARTILE({1,2,4,7,8,9,10,12},1) equals 3.5
