NOAA Storm Database Analysis: Health and Economic Impacts of Severe Weather Events For this assignment, I first loaded the data and examined the column names, noting that the event type column (EVTYPE) contained many duplicate entries. The data required cleaning, so I consulted the data codebook to define the event types and performed transformations to map EVTYPE to standardized event types. I analyzed human damage, economic impact, and property damage separately. I combined the PROPDMG, PROPDMGEXP, CROPDMG, and CROPDMGEXP columns, converting the “K”, “M”, and “B” factors into numeric values for analysis. The results show that Tornado has the greatest impact on human damage, while Flood has the most significant economic consequences.
