Q5. The data for this challenge can be analyzed either as a static collection or as a dynamic stream of data, as it would occur in a real emergency. Describe how you analyzed the data - as a static collection or a stream. How do you think this choice affected your analysis?
I analysed the data as a static collection. By looking at the data as static collection, we are able to analyse the overall data and draw conclusions about trends and patterns occurring across the period. As compared to analysing the data as a dynamic stream, it is much easier to identify clusters or gaps, and thus more valuable insights can be gleaned. On top of that, static collection analysis also allows for the accuracy of the data to be verified. For example, when examining an increase in reading from a sensor, the user can quickly spot if it is an anomaly or indeed an increase in radiation in the region. By analysing the data as a static collection, I can also make analysis of which sensors are reliable and functioning, and which faulty sensors’ data to remove before drawing insights from the dataset.
