to me, i think it should be the summation of group 2 category1 + category 2

OpenStudy (twizttiez):

Brb man

OpenStudy (twizttiez):

OpenStudy (lyrae):

What do you think? Did you read what GIL.ojei wrote?

OpenStudy (twizttiez):

I didn't really understand it :/ i suck at math

OpenStudy (lyrae):

Nah don't say that! Everyone needs practice! He meant that everyone in Group 2 is the total (sum) of the Group 2 row.

OpenStudy (twizttiez):

so i would add 24 to 19?

OpenStudy (anonymous):

that is 19 + 23 = 42

OpenStudy (lyrae):

What's the difference between a row and a column?

OpenStudy (twizttiez):

o.o ummmmm

OpenStudy (anonymous):

24 and 19 are the column

OpenStudy (lyrae):

Rows are horizontal whilst columns are vertical, so what you wrote would be the sum of people in Category A column.
