Note:
Significance is shown above the chi-square test-result in each cell; degree of freedom =1 in each case; ( 3.84 <= chi-square < 6.63) for significance 0.05 (shown in
green) and chi-square >= 6.63 for significance 0.01 (shown in red). Brackets indicate that one or more expected values in the test was less than the recommended 5. Statistics following Statistics for Ornithologists, Jim Fowler and Louis Cohen, BTO Guide 22 (undated).© Copyright Nick Rossiter 2002.
