2. “What follows?” Unintentional Effects Noticed that there are certain areas and certain time zones where earthquake data are likely to be missing. This finding will help enhance future data collection. Also discovered the relationships between earthquakes and weather. • “Helpful to whom else?”Other Users Insurance companies are likely to be interested in this analysis. The relationships between earthquakes and weather may be interesting to meteorologists. “Any tips?” Tips for Data Analysis • “What for?” Intention / Aim of Data Analysis • Discovering hidden patterns of earthquakes • Analysis Tool / Method 1:Apriori • Expected Outcomes 1:Areas tending to quake simultaneouslyor consecutively. • Ex.
