My code is listed below, I'm trying to figure out what the problem is and what I can do to fix it. The output i'm getting is:
Name Low High Average
0 0 0.00
The correct output I want is the name of the Assignment, the lowest score and highest score obtained, and the Average Score under each column. Can Someone help and point me in the right direction
awk 'BEGIN{
FS = " "
print "Name Low High Average"
i=0
}
{
if(i==0){
i+=1
}
else{
if(low[$3]<$4)
low[$3] = $4
if(high[$3]>$4 || high[$3]==0)
high[$3] = $4
avg[$3] += $4
cnt[$3] += 1
}
}
END{
for(k in low){
avg[k] = avg[k]/cnt[k]
printf "%s %d %d %.2f ",k, low[k], high[k], avg[k]
}
}' ./Lab03-data.csv
Hmmm....csv file, but you're setting your FS=" " ?
Heres the sample file:

Maybe try massaging the file before the awk . Using the sample posted:
tr " " '
' < sample_file | awk '
NR<6 {next}
{printf $0 FS}
!(NR % 5) {print _}
' | awk ...(your awk)...
So just to be clear, I insert the coding you provided in front of mine and insert my coding where it says your awk correct?
I doubt your sample file is what you actually have.post #3 edited by me using the code tags.

To cast your file into single line records, try
$ paste -sd"\t\t\t\t\n" <(tr -s ' ' $'\n' <file)
Student Catehory Assignment Score Possible
Chelsey Homework H01 90 100
Chelsey Homework H02 89 100
Chelsey Lab L01 91 100
Chelsey Lab L02 100 100
.
.
.
EDIT: How far would this get you:
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]

Hi Marquez3105,

Try also (no file preformatting needed):
awk '
BEGIN {print "Name\tLow\tHigh\tAverage"
}
{for (i=6; i<NF; i+=5) {if (!($i in MIN)) MIN[$i] = 1E100
if (MIN[$i]>$(i+3)) MIN[$i] = $(i+3)
if (MAX[$i]<$(i+3)) MAX[$i] = $(i+3)
SUM[$i] += $(i+3)
CNT[$i]++
}
}
END {for (m in MAX) print m, MIN[m], MAX[m], SUM[m]/CNT[m]
}
