"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

1

,
๐
3
,
โฆ
,
๐
๐
a
1
,a
2
,a

,โฆ,a
n
, then the sum of these numbers can be denoted as
โ
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 (

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
