Question 1051018
We are asked to analyze an association between two categorical variables
:
We start by summing the rows and columns of our table
:
Fine --4 20 8---32 
Medium 5 23 12--40
Coarse 21 23 4--48
:
-------30-66-24-120
:
From the above information we can calculate the row and column percentages
:
Fine --0.125-0.625-0.25-100.0
Medium-0.125-0.575-0.30-100.0
Coarse-0.4375-0.479-0.08-100.00
:
-------0.25---0.55--0.20-100.0
:
Note that our two categorical variables(texture and color) are related in the sample if at least two rows of percentages noticeably differ in the pattern of row percents
:
*************************************************
the pattern of percentages is the same, therefore
texture and color are not related
