Document Summary
)t"s rare we have access to two entire populations, consequently, we obtain samples from the two populations. Another application of the hypothesis test procedure is to compare two or more samples with sample data drawn randomly from those populations. Today we will focus on comparing two samples; next week we will extend the analysis to consider three or more samples. Do men that migrate within their country to find work make more than men who not migrate: 2 populations of men, get sample from each group and make a comparison of wages. Procedure 2: more common for binary or dichotomous variables. Example: cdn gss survey (women vs men) (employed vs unemployed) We can specify the direction of the difference (one tailed test) or merely specify that there should be. As we follow the 5-step procedure for hypothesis testing, there are several changes that distinguish the two-sample hypothesis test from the one-sample hypothesis test we discussed last week:
