Trend
Understanding the Overall Trend
Upon analyzing the provided data, it appears that the exchange rates generally show an increasing trend over the period. If we compare the starting value of 0.15938 on 2024-03-29 with the ending value of 0.16113 on 2024-04-26, there is a clear increase. However, it's also important to note that within this overall increasing trend, there are minor fluctuations with periods of both increases and declines.
Seasonality or Recurring Patterns
In terms of seasonality or recurring patterns, the dataset doesn't immediately reveal any apparent daily or weekly patterns. It is worth noting that the exchange rate values don't seem to change significantly on specific days of the week or specific times within a day. It can suggest that within the period covered by the dataset, the rates are somewhat random and do not exhibit deterministic seasonality. However, a more in-depth time series decomposition analysis would be needed to conclusively determine the lack of seasonality.
Identifying Outliers
The dataset includes some instances where the exchange rate changes fairly rapidly compared to the overall trend. Notable spikes and declines could be considered as outliers. For example, the jump from 0.1597 at 2024-04-10 06:00:02 to 0.16076 at 2024-04-10 08:00:03 and the subsequent increase to 0.16129 by 2024-04-10 14:00:03, represents an unusually high rate of increase within a short period. Moreover, the drop from 0.16245 at 2024-04-22 12:00:03 to 0.16154 at 2024-04-22 14:00:03 also stands out when looking at the overall trend.
Note: Statistical methods, such as the Z-score or the IQR method, can be used for a more precise identification of outliers beyond this visual examination.
