If 0i, (i=1,2, ,n) is a set of observed (experimental frequencies )and ei (i=1,2, ,n) is the corresponding set of expected (theoretical or hypothetical) frequencies, then, df. The number of yiest cells counted in a haemocytometer is compared to the theoretical value is given below. H1: the esperimental results does not support the theory. Table value: (6-1=5 at 5 % l. os)= 11. 070. We accept the null hypothesis. (i. e) there is a good correspondence between theory and experiment. test for independence of attributes. 2 m= number of rows n= number of columns.
