Come up with a 2 x 2 contingency table for
which p^1=p^2 , and for which the row and column
totals are not the same. Now calculate χ2*. Are
you surprised? Why or why not?
Discussion 1 : Part 2 of 2 : Work in Groups and come up with a
simple survey for Voice of customer on a new Pho-Let (Phone &
Tablet combined) as to what they think the features and
requirements should be:

A contingency table, also called a two-way table, is made up of
r rows and c columns. In general, how many cells are in a
contingency table with r rows and c columns?
1) r x c (r times c)
2) (r-1)(c-1)
3) r + c
In general, how many degrees of freedom are associated with a
contingency table with r rows and c columns?
1) r + c
2) r times c
3) (r-1)(c-1)
