+## Analysis
+
+The computed correlation between WO and NL Beer consumption measures a linear association. However, by visual inspection, the NL Beer consumption series does not follow a linear trend: it remains roughly steady until 2014 and then rises sharply, almost exponentially. In contrast, the WO student population increases steadily over the entire period. This suggests that a simple linear regression would not fit NL Beer consumption well, and the high correlation mainly reflects the late increase rather than a consistent relationship throughout. Therefore, while correlation gives a first indication of association, it does not fully capture the temporal dynamics of the data
