"Sigma" is the Greek letter ฮฃ, which is commonly used in mathematics and statistics to represent summation. In mathematical equations, it signifies the sum of a sequence of numbers or terms. For instance, if you have a series of numbers
๐
1
,
๐
2
,
๐
3
,
โฆ
,
๐
๐
a
1
,a
2
,a
3
,โฆ,a
n
, then the sum of these numbers can be denoted as
โ
๐
=
1
๐
๐
๐
โ
i=1
n
a
i
, where
โ
โ represents the summation symbol,
๐
i is the index of summation (it starts at
1
1 and goes up to
๐
n), and
๐
๐
a
i
represents each individual term in the series.
In statistics, sigma (
๐
ฯ) is also used to represent the standard deviation of a population, or the spread of data points around the mean. This usage is particularly common in fields like probability theory and data analysis - Made by ChatGPT because i am NOT writing all that

โErm, what the sigmaโ is a humorous and sarcastic expression used to convey shock, confusion, or disbelief. The phrase merges "erm"โa filler word indicating hesitation or puzzlementโwith "what the sigma," a playful reference to the concept of a "sigma male," which is often associated with a lone, self-reliant persona in popular culture. The term is meant to be taken in a tongue-in-cheek manner, adopting a tone similar to that of Squidward from SpongeBob SquarePants, known for his deadpan and exasperated reactions. This expression is used to mockingly elevate the level of bewilderment in a situation, adding a layer of ironic seriousness.
