ok do you know how to calculate conditional relative frequencies?
bobobox
  • bobobox
Nope Thats why I need you
jim_thompson5910
  • jim_thompson5910
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

focus on the pop column what is the difference in proportion between male and female?
bobobox
  • bobobox
i hear the word difference it make me want to subtract
jim_thompson5910
  • jim_thompson5910
yep you subtract
bobobox
  • bobobox
0.4285146
jim_thompson5910
  • jim_thompson5910
now do the same for rap
bobobox
  • bobobox
okay
bobobox
  • bobobox
0.6
jim_thompson5910
  • jim_thompson5910
which difference is larger
bobobox
  • bobobox
rap
jim_thompson5910
  • jim_thompson5910
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`
bobobox
  • bobobox
okay
bobobox
  • bobobox
im sorry do you think you oculd simplify that for me?
jim_thompson5910
  • jim_thompson5910
The larger difference in rap means that more males like rap than females. So this is considered positive association.
jim_thompson5910
  • jim_thompson5910
If the two conditional relative frequencies were nearly identical, then there would be weak to no association (ie the two would be independent)
jim_thompson5910
  • jim_thompson5910
this tells us the variables are connected in some way
bobobox
  • bobobox
okay so would it be d or are we not close to the answer yet... thats my guess becuase it discusses rap
jim_thompson5910
  • jim_thompson5910
yeah I'm thinking D as well because of the largest difference
bobobox
  • bobobox
we have to be positive with all of the answers
