I&#x27;m not sure why an ad that only tells its readership &quot;it&#x27;s too complex, just use our product&quot; was posted here.<p>While I&#x27;m new to this field myself, the standard score[1] and interquartile range[2] algorithms can be utilized for this purpose, where the underlying calculations use a &quot;streaming&quot; algorithm eliminating the need for storage, such as [3].<p>I recently used some of this to monitor abnormally high request times for an application at my workplace.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Standard_score" rel="nofollow noreferrer">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Standard_score</a><p>[2] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Interquartile_range" rel="nofollow noreferrer">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Interquartile_range</a><p>[3] <a href="https:&#x2F;&#x2F;nestedsoftware.com&#x2F;2018&#x2F;03&#x2F;27&#x2F;calculating-standard-deviation-on-streaming-data-253l.23919.html" rel="nofollow noreferrer">https:&#x2F;&#x2F;nestedsoftware.com&#x2F;2018&#x2F;03&#x2F;27&#x2F;calculating-standard-d...</a>

I’ve used Inter-Quartile Range for detecting anomalies and found it pretty decent and without needing tons of dependencies or ML, just some C#.<p>How does it compare to other methods?<p><a href="https:&#x2F;&#x2F;www.yourdatateacher.com&#x2F;2021&#x2F;11&#x2F;01&#x2F;outlier-identification-using-interquartile-range&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.yourdatateacher.com&#x2F;2021&#x2F;11&#x2F;01&#x2F;outlier-identific...</a>
