Relative tables help!

@jim_thompson5910
sorry I was working on a spreadsheet for this
Yeah thats okay as long as I learn and get it right!
ok do you know how to calculate conditional relative frequencies?
Nope Thats why I need you
you need to calculate conditional relative frequencies with respect to the columns so what you do is divide everything in column 1 by 280 (since this is the total) divide everything in column 2 by 210 divide everything in column 3 by 100 etc etc
okay
one second let my make a spreadsheet
sure thing
@jim_thompson5910
you should have divided the last row by itself, but that doesn't matter really
okay
focus on the pop column what is the difference in proportion between male and female?
i hear the word difference it make me want to subtract
yep you subtract
0.4285146
now do the same for rap
okay
0.6
which difference is larger
rap
so according to this http://mathbitsnotebook.com/Algebra1/StatisticsReg/ST2TwoWayTable.html it says `The bigger the differences in the conditional relative frequencies, the stronger the association between the variables`
okay
im sorry do you think you oculd simplify that for me?
The larger difference in rap means that more males like rap than females. So this is considered positive association.
If the two conditional relative frequencies were nearly identical, then there would be weak to no association (ie the two would be independent)
this tells us the variables are connected in some way
okay so would it be d or are we not close to the answer yet... thats my guess becuase it discusses rap
yeah I'm thinking D as well because of the largest difference
we have to be positive with all of the answers
i can't have any slip ups
are we ready for me to submit the assignment? If I get under 70 I won't be able to take my final exam
I'm pretty sure, but others can chime in too if they want
I am going to submit, It will tell me the answers instantly
@bobobox do you find out the answer right away or does that take a while?
@UsukiDoll The answer was Correct!!!!!!
that's good! :D
