To cast your file into single line records, try

Code:
$ paste -sd"\t\t\t\t\n" <(tr -s ' ' $'\n' <file)

EDIT: How far would this get you:

Code:
paste -sd"\t\t\t\t\n" <(tr -s ' ' $'\n' <file) | awk '
BEGIN           {print "Name\tLow\tHigh\tAverage"
                }
NR == 1         {next
                }
!($1 in MIN)    {MIN[$1] = 1E100
                }
                {if (MIN[$1]>$4) MIN[$1] = $4
                 if (MAX[$1]<$4) MAX[$1] = $4
                 SUM[$1] += $4
                 CNT[$1]++
                }
END             {for (m in MAX) print m, MIN[m], MAX[m], SUM[m]/CNT[m]
                }
