Total newb to stats: I'm an embedded programmer with a BSEE, so I like to think I've got lots of knowledge with the least possible amount of applicability to real life.
I built a test bench to observe the output of a sensor and came up with an algorithm to quantify an anomaly I observed in the data. I wanted to know what to call it, so I asked on Math.SE what is the average of an integral. While continuing to research related questions on Math.SE for a week, I just saw someone said their similar-ish question was answered on here...
Could I please get help with which tags to use to post the Math.SE question on here? Or if this is really trivial, I'd appreciate a pat on the back and "it is $__________$, duh!" for an answer.
Note that in the stackoverflow alagorithm link above, I mention that standard deviation, skewness, nor Kurtosis help. Also that I have known data, so my problem isn't helped with estimation tools like linear regression.
Basically, I came up with a way to quantify the "dip" in this figure and want to know what that process is called:
