An awk approach:-
Code:
awk '
        {
                A[$1] += $2
                T[$1] += ( $2 == 0 ? 0 : 1 )
        }
        END {
                for ( k in A )
                        print k, ( T[k] ? A[k] / T[k] : 0 )
        }
' file

Use sort if you want to sort the results by first column:-
Code:
' file | sort

NAME
git-column - Display data in columns SYNOPSIS
git column [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>] [--indent=<string>] [--nl=<string>] [--padding=<n>] DESCRIPTION
This command formats its input into multiple columns. OPTIONS
--command=<name> Look up layout mode using configuration variable column.<name> and column.ui. --mode=<mode> Specify layout mode. See configuration variable column.ui for option syntax. --raw-mode=<n> Same as --mode but take mode encoded as a number. This is mainly used by other commands that have already parsed layout mode. --width=<width> Specify the terminal width. By default git column will detect the terminal width, or fall back to 80 if it is unable to do so. --indent=<string> String to be printed at the beginning of each line. --nl=<N> String to be printed at the end of each line, including newline character. --padding=<N> The number of spaces between columns. One space by default. GIT
