TWO WAY CHI SQUARE You have the following data regarding Gun Ownership and Sex Gender Own Gun? Male Female Total Yes 32 30 No 71 114 Total Null Hypothesis: Research Hypothesis: Compute a Chi Square test of significance Formula for Chi Square Chi Square f e = expected frequencies = e e o f f f 2 2 ) ( χ f o = observed frequencies For Two way f e = (column total)(row total) N (two way) df = (r – 1)(c – 1) r = the number of rows c = the number of columns You will create a table again to calculate the chi square for a two way test, the main difference here is how you
