In this lab we will again use data that we originally looked at in lab one. That data provided three types of weather data for cites that were located on the west coast, in the mid west and on the east coast. In lab one you chose one of the three weather measurements (precipitation, Ave. Jan. temp or Ave. July temp). For lab one I asked you to find descriptive information (means and standard deviations) for each region and to describe how those regions differed. Now, we will use the statistical test of one way ANOVA and post hoc testing to identify if there are differences beyond what would be expected by chance, between geographic regions. In case you do not still have the data from lab one you can find the list of data in the Lab materials folder under the Lab One Data option. While you do not need to analyze the same weather data for lab four you are welcome to stick with the same data so that you can see how your "eye ball" evaluation of differences is the same or different from a statistical evaluation of differences.

1) Define the population from which these three samples have been selected.
