Average calculation based on number of rows

Dear users,

I need your support, I have a file like this:

Code:
272134.548 6680572.715
272134.545 6680572.711
272134.546 6680572.713
272134.548 6680572.706
272134.545 6680572.721
272134.543 6680572.710
272134.544 6680572.715
272134.543 6680572.705
272134.540 6680572.720
272134.544 6680572.721
 
272134.539 6680572.714
272134.260 6680573.092

272101.962 6680565.280
272101.903 6680565.156
272101.912 6680565.159
272101.912 6680565.156
272101.905 6680565.158
272101.899 6680565.169
272101.899 6680565.161
272101.894 6680565.173
272101.894 6680565.169

And I need to get the first values block before the row without data (then the second values block before the blanck line and so on), and calculate the simple average value for each row, this is, sum all numbers and divide it by the number of values. I did the following bucle to separate the first values until it finds the blank line but doesn't work:

Code:
while read file
do
        file=($list.txt)
        awk '{ print $1, $2 }' file | awk NF | echo ""${line[0]}" "${line[1]""
done

Separately, I used wc -l to count the values but the file name appears (let's say: wc -l list.txt gives 10 list.txt).

I would appreciate your support to solve my problem.

Thanks in advance.

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME
Locale::Codes::LangFam - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangFam; $lext = code2langfam('apa'); # $lext gets 'Apache languages' $code = langfam2code('Apache languages'); # $code gets 'apa' @codes = all_langfam_codes(); @names = all_langfam_names(); DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in ISO 639-5. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5 language family codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $lext = code2langfam('apa','alpha'); $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages. This is the default code set. ROUTINES
code2langfam ( CODE [,CODESET] ) langfam2code ( NAME [,CODESET] ) langfam_code2code ( CODE ,CODESET ,CODESET2 ) all_langfam_codes ( [CODESET] ) all_langfam_names ( [CODESET] ) Locale::Codes::LangFam::rename_langfam ( CODE ,NEW_NAME [,CODESET] ) Locale::Codes::LangFam::add_langfam ( CODE ,NAME [,CODESET] ) Locale::Codes::LangFam::delete_langfam ( CODE [,CODESET] ) Locale::Codes::LangFam::add_langfam_alias ( NAME ,NEW_NAME ) Locale::Codes::LangFam::delete_langfam_alias ( NAME ) Locale::Codes::LangFam::rename_langfam_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangFam::add_langfam_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Codes::LangFam::delete_langfam_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
