The Use and Misuse of Chi-Square: Lewis and Burke Revisited
... expected frequencies that are too small the most common weakness in the use of chisquare (p. 460). They took the position that expected values of 5 were probably too low and stated a preference for a minimum expected value of 10, with 5 as the absolute lowest limit. Lewis and Burke cited as examples ...

For example, if we measure the weights of a population of individuals and plot it, the graph will represent a normal di ...
