Question Awk- Pivot Table Averages
Hi everyone,

Has anyone figured out yet how to do pivot table averages using AWK. I didn't see anything with regards to doing averages.

For example, suppose you have the following table with various individuals and their scores in round1 and round2:

Code:
SAMPLE    SCORE1    SCORE2
British    15    19.5
British    7    9.1
British    8    10.4
British    11    14.3
German    6    7.8
German    7    9.1
Italian    10    13
Italian    3    3.9
Italian    19    24.7
Italian    9    11.7
Italian    6    7.8

The objective is to do a pivot table using Awk to calculate the average scores by country such as shown in the output below.

Code:
POPULATION    AVG SCORE1    AVG SCORE2
British    10.25    13.33
German    6.50    8.45
Italian    9.40    12.22


Any ideas how to do this using Awk?

ptbl

PTBL(1) 						      General Commands Manual							   PTBL(1)

NAME

       ptbl - print a type table

SYNOPSIS

       ptbl [-a] <tbl-file>

DESCRIPTION

       ptbl  prints  the  give	type table to stdout.  It will print it in one of two formats: internal style and ASN.1 stlye.	The internal style
       shows the contents of the type table data structure in ASN.1 value notation.  You will need to look at the tbl.asn1 file to understand  the
       internal form.  The ASN.1 form attempts to re-create the ASN.1 that generated the given type table.

OPTIONS

       -a     Print the table in ASN.1 style (recommended)

FILES

       snacc/tbl-tools/ptbl/	   Source code for the ptbl program snacc/asn1specs/tbl.asn1 ASN.1 definition for the type table data structure

BUGS

       ptbl does not attempt to print the IMPORTs information even though it is possible with a bit of work.
