Explanation Consider the following contingency table of observed values of preferred cereal brands for a random sample of adults is given below, Observed Sample of 146 Adults Brand A Brand B Brand C Brand D Total Male 28 14 11 27 80 Female 9 16 8 33 66 Total 37 30 19 60 146 Formula for calculating expected value of a frequency in a contingency table: The expected value of the frequency for the i th possible outcome in a contingency table is given by E i = ( r o w t o t a l ) ( c o l u m n t o t a l ) n Where n is the sample size. From the above table represent the value of n is 146. The expected value of brand A for the random sample of male is given below, E brand A and male = 80 × 37 146 = 2960 146 = 20.27397 The expected value of brand B for the random sample of male is given below, E brand B and male = 80 × 30 146 = 2400 146 = 16.43836 The expected value of brand C for the random sample of male is given below, E brand C and male = 80 × 19 146 = 1520 146 = 10.41096 The expected value of brand D for the random sample of male is given below, E brand D and male = 80 × 60 146 = 4800 146 = 32.87671 The expected value of brand A for the random sample of female is given below,
