Marginal Frequencies question: I'll medal

OpenStudy (howard-wolowitz):

@Vocaloid i dont get it

Vocaloid (vocaloid):

each of the three age groups has its own marginal frequemcy to find the marginal frequency of the under 30 group, add up all the numbers in the row

Vocaloid (vocaloid):

|dw:1447379575697:dw|

OpenStudy (howard-wolowitz):

what are the three numbers

OpenStudy (phi):

add up the 3 numbers in the first row: 196, 138, and 89 then do the same for the next row, and the last row

OpenStudy (howard-wolowitz):

ok i got 423

OpenStudy (phi):

that is the first of the 3 numbers that are the answer to marginal frequencies of the age groups. now add up the 3 numbers in the next row.

OpenStudy (howard-wolowitz):

so 341

OpenStudy (phi):

yes, and the last number of the answer is the sum of the 3 numbers in the "over 60" row

OpenStudy (howard-wolowitz):

last row is 346

OpenStudy (howard-wolowitz):

wait.. so its the last number in the last three answers?

OpenStudy (phi):

yes, so the answer to marginal frequencies of the age groups is 423, 341, and 346

OpenStudy (howard-wolowitz):

ok i see then how would we get the last answer were looking for?

OpenStudy (phi):

The answer to the marginal frequency of the political parties are the numbers (totals) in the very last row.

OpenStudy (phi):

in other words, the sum of each column

OpenStudy (howard-wolowitz):

ok so just add up and down and I'll tell u what i get for each

OpenStudy (phi):

yes. If you already filled in the "totals" you have those numbers

OpenStudy (howard-wolowitz):

First row: 459 Second row: 420 Third row: 231

OpenStudy (phi):

yes, but up/down are called columns (not rows. rows go sideways) but yes, those are the answer to marginal frequencies of the political parties

OpenStudy (howard-wolowitz):

oh ok thank you for helping me and the advice
