Step 2: Uncertainty Qualitative Analysis
After getting the locations with a more significant number of records, we can make an analysis of factors that might cause uncertainty in the data points.
Firstly, I studied the data points for Easton (Refer to Figure 2.2). Easton is one of the location that was identified to be the top few locations which was hit the hardest by the Major Quake from 7 to 11 am on the 8th April. However, as we can see after the Major quake the Shake Intensity Rating is decreasing over time as marked out in Figure 2.2. Similarly, when you look at the Calendar Heat Map for the other variables in the reports that came in over 24 hours after the Major quake, it has gradually dropped in Rating value and the number of reports coming in is decreasing as well. Thus, showing signs that the major quake is over, and the conditions are improving.
Secondly, for Old Town (Refer to Figure 2.3). Old town was also one of the locations identified to be the top few locations which were hit the hardest by the Major Quake. However, there were too many missing data points to make any conclusion to whether the data points over the time period from 6th to 11th April are reliable.
Thirdly, for Northwest (Refer to Figure 2.4). Northwest was within the impacted area of effect from the Major Quake shake map provided for reference. However, during the occurrence of the Major Quake, the users have provided low ratings in both shake intensity and the other variables. Hence, even though the number of reports that are not within the Certain Interval Range(Box plot range) is low, I would not classify the data points for this location in its entirety to be reliable to follow.
Next, for Broadview (Refer to Figure 2.5). Broadview was not within the impacted area of effect from the Major Quake shake map. However, looking at its data points during the Major Quake and 24 hours after that, even with the missing data, we could assume that Broadview was hit at the very least harder than Northwest which got up to the top 5 chosen location that has been hit the hardest in the previous question. This could only suggest the Major quake shake map provided or the datapoints input by the population is unreliable.
Lastly, for East Parton (Refer to Figure 2.6). North Parton follows the same analysis as Easton where the rating value for shake intensity gradually decreases, which aligns the recovering from the major quake and its data points are also gradually dropping in the Number of Records. Hence, this report is realistic and reliable to be used.
