What is statistical significance?
Statistical significance is a mathematical method to determine if a result is genuine or the result of random chance. Thematic will highlight some difference in theme volume as statistically significant to help you identify more insightful changes.
Thematic will mark a difference as statistically significant if there is a 5% or less chance the difference is because of randomness. This means the difference can be considered genuine and not because of random chance.
Examples of statistical significance
The difference in 'leg room' mentions in 4+ star reviews and 1-3 star reviews is not statistically significant. This means the difference may be caused by random chance and not a genuine difference.
The difference in 'missed flight' mentions between 4+ star reviews and 1-3 star reviews is statistically significant. This means the difference can be reliably assumed as genuine and not because of random chance.
