Reply #155: Sorry, LC. Joe's right in #143, and I was confused in #142

The ballot orders are treated symmetrically when counting the number of different ballot orders per cluster.

In the comparison I was making, between distribution of ballot orders by cluster size and distribution of ballot orders by number of different orders, the latter should shift locations from column to column equally from all rows.

In your table, it looks as though the columns are roughly even except for two pairs of adjacent cells.

In the first row, column 3 is 85 and column 4 is 115. If these statistics were instead 100 and 100, the columns would be closer to balancing.

In the fourth row, columns 4 and 5 are 87 and 49. If instead these cells were 100 and 36, the columns most likely would reject an F-test for the hypothesis that the columns are different.

Sorry for my confusion--I was tired and rushed when I wrote #142.
