Step: how large is the sample large because above 100. Step 3: sampling distribution z because large. Find z critical : +1. 65 (go to c region in table) if asking for signif difference its two talled. Step 4: z obtained mean 1 mean 2 // variance x-x(pooled estimate) Step 2: h0 pu1=pu2 pu1 not= pu2 (because signig difference, p because pop. Step3: alpha 0. 10 ,z critical +-1. 65 (+- because signif, divide alpha by 2). Criteria for causality: 1. association or correlation between variables: establishment of time order, elimination of alternatives. Bivariate associations can be investigated by: does an association exist. 0 -10 percent difference weak, 11-40 moderate, 30+ strong pattern of relationship which variables go together direction if both variables ordinal we can discuss direction in positive relationships the variables vary in same direction. In negative the they vary in opposite directions.
