Introduction : 

This KB explains how the trend analytics graph / box plots are calculated for the Sentiment score graph.

1. Data Grouping:

• The data is grouped by month based on the creation date of each data point.

2. Box Plot Calculation:

• Quartiles:
  • Q1 Lower Quartile (25th percentile): Represents the value below which 25% of the data within the month falls.
  • Q3 Upper Quartile (75th percentile): Represents the value below which 75% of the data within the month falls.
• Interquartile Range (IQR): Calculated as Q3 - Q1.
• Median: The middle value of the "Sentiment Score" data for that month.
• Maximum: Q3 + (1.5 * IQR)
• Minimum: Q1 - (1.5 * IQR)

3. Outliers:

• Data points within a month that fall outside the range defined by the calculated Maximum and Minimum values are considered outliers. These are typically represented by red dots on the box plot.
