Help! i have a question

Hi dear friends

 

theses days i was working on a data mining project for the first time and i faced with a problem

 

my data set was included of the result of 3 questions about 7 kind of sofa 

for example:

which sofa do you prefer from quality aspect??

the answer could be from 1 to 7

and

which sofa do you prefer from price aspect??

and 3rd one was about color

 

so the result was a matrix of 100 people which were asked these questions with 3 column that were integer numbers from 1 to 7

 

now i wanted to apply association rule on this data set in rapid miner 
and i expected to have such results : people have chosen first sofa from quality aspect usually have chosen third sofa from price aspect

 

but it was impossible because association rule module in rapid miner only works with Binominal data sets as you know ...

do you have any idea how can i solve this problem???

thanks for your help

    You'll have to convert your data set using the Nominal to Numerical operator, set at Dummy Coding. That will create new attribute columns but with 1's and 0's. From there you can use the Numerical to Binominal operator to convert them to true and falses.
