Step one: Add the totals for each column (these are in yellow in the table). For example total male participants = 16 + 6 + 4 = 26 – Total number of male and females with earphones in their ears = 16 + 15 = 31 Step two: Next, the expected frequencies for each cell need to be calculated. Formula to use is below: Expected Frequencies = For example, with the first cell in the table (males/earphones in ears) Expected value = 6.24 for males wearing earphones Example (2) Expected Value for females wearing earphones Step three: Expected values for each cell should be calculated. Male Female Raw total Earphones in Ears 16 (observed) 15 (observed) 31 31 x 26/50 = 31 x 24/50 = 16.12 (expected) 14.88 (expected) No earphones in ears 6 (observed) 6 (observed) 12 12 x 26/50 = 24 x 12/50 = 6.24 (expected) 5.76 (expected) Earphones dangling 4 (observed) 3 (observed) 7 around neck 7 x 26 /50 = 7 x 24 / 50 = 3.64 (expected) 3.36 (expected) Column total 26 24 50 Step four: Calculating Chi Square –
