Cochran Criteria

By "Cochran Criteria," I am referring to the standard assumptions required for the goodness-of-fit test to be valid, in particular:

Quote:

Expected cell count – Adequate expected cell counts. Some require 5 or more, and others require 10 or more. A common rule is 5 or more in all cells of a 2-by-2 table, and 5 or more in 80% of cells in larger tables, but no cells with zero expected count.

This link is more along the lines of what I'm thinking:

Quote:

"No more than 20% of the expected counts are less than 5 and all individual expected counts are 1 or greater" (Yates, Moore & McCabe, 1999, p. 734).

Do we assume that these assumptions always hold for problems in C?
