Using a one-way ANOVA with unstacked columns

In the first activity, we will use the one-way ANOVA to check the differences between population means across several groups of data. We will be using atmospheric data for the North Atlantic Oscillation (NAO). The NAO is an important climatic phenomenon that affects the North Atlantic. Variations in the NAO affect the weather across Europe. Measurements of the pressure difference between the northern weather station in Iceland and more southerly stations are an important measure of this phenomenon.

Here, we will use the one-way ANOVA to investigate the effect of the pressure difference across months.

This data was obtained from the Climactic Research Unit and is located at http://www.cru.uea.ac.uk/cru/data/nao/ ...
