Sigma symbol meaning
The Greek symbol sigma is the same as the letter ‘S' of the English alphabet. Even though it was the twentieth letter in Old and Ancient Greek, in the modern era it is the eighteenth letter of the Greek alphabet. Sigma can be symbolized in two ways-the uppercase sigma Σ and the lowercase sigma σ.
In mathematics, the upper case sigma (Σ) is used to indicate a summation notation (sum of a discrete set or series of numbers) and the lower case sigma (σ) is the mathematical symbol (how is sign and symbol different on askanydifference) which stands for standard deviation which is commonly used as a measure of the variation of a set of values. Though the two sigma symbols may look exceedingly dissimilar to the letter S, the uppercase sigma (Σ) is indeed the Greek equivalent of the capital letter ‘S' and the lowercase sigma (σ) is equivalent to the small letter ‘s'.
History of sigma
The position of the alphabet and the shape of the uppercase and lowercase sigma symbols were derived from the Phoenician letter W (shin). The original name sigma was initially coined as ‘san' but later san was recognized as a separate letter in the Greek alphabet, and is now represented as the letter Ϻ. According to the ancient Greek historian Herodotus, the name san was decided by the Dorians for the same letter which was referred to as sigma by the lonians.
During the Hellenistic period, the upper case sigma Σ was abridged to a C-like shape in handwritten Greek. It was found on coins during the 4th century BC and was also considered the universal standard of sigma during the middle ages. Today, it is well known as a Lunate sigma as it resembles the shape of a crescent and is widely used in Greece, classical Greek texts, and religious places of worship. It was the beginning of the 8th century BC when sigma was adopted in Old Italic alphabets.

How to insert a Sigma Symbol in Word
Microsoft word provides us with a long list of foreign alphabets, text symbols, and special characters. Though most of these symbols and characters may not appear on the keyboard, they can still be added to your document with just a couple of clicks. A few methods one can use to obtain a sigma symbol from word are listed as follows:
1. The symbol menu
Joyride galaxy mac os. To employ this method, one must click on the Insert tab and find the ‘Symbol' option at the far right-hand corner of the ribbon. Once the user selects this option, he'll come across a small list of popular symbols. If the user doesn't find the sigma symbol in that list, he should then click on ‘More symbols'. Soon after, a dialog box appears which displays a variety of symbols, letters, and characters. To quicken the search for Greek alphabets (which in our case is sigma) the user can select the subset called ‘Greek and Coptic'. Once the user finds the sigma symbol, he should click on insert to add the symbol to the document.
2. Symbol's code
One can also obtain the sigma symbol on their page by typing the symbol code along with an ‘Alt+X' combination. The uppercase sigma symbol code is 2211, and has to be accompanied with the keyboard shortcut ‘Alt+X' to get ∑. The code ‘03C3', along with the shortcut ‘Alt+X', gives us the lowercase sigma symbol σ.
3. The font symbol
To insert an uppercase sigma symbol, one can type the capital letter ‘S', highlight the letter (by double-clicking on the letter) and follow it with a Ctrl+Shift+Q combination to get an S. Similarly, to obtain a lowercase sigma symbol, one must type the small letter ‘s', highlight the letter, and press the Ctrl+Shift+q combination to get an s.
4. Substitute text with symbols by creating shortcuts

How to insert Sigma Symbol with keyboard
A sigma symbol can be easily obtained in your sheets or text by using basic keyboard shortcuts.
Windows
In Windows operating system, the uppercase sigma Σ can be obtained by typing the numbers ‘2211', followed by the keyboard shortcut ‘Alt+X' to get Σ. Similarly, to obtain a lowercase sigma σ, one must type ‘03C3' and then press ‘Alt+X' subsequently to get σ.
Macintosh operating system
In Macintosh operating system, however, the uppercase sigma Σ and the lowercase sigma σ are procured by a different method. To obtain a sigma symbol in Mac OS, one must first click on the Apple menu, go to system preferences, choose the ‘Keyboard' icon, and enable the ‘keyboard and character viewer' option. Next, at the top-right-hand corner of the screen, there will be a drop-down list where one has to select the ‘Character Viewer' option and search for the character he wants want to add (in our case, the sigma symbol).
Once that is done, the user can either insert it directly to his text or if he wants to add new shortcuts which would directly give him the sigma symbol the next time he uses these text substitutions.

How do you make a sigma symbol in LaTeX?
LaTeX is a markup language used to typeset high-quality documents. It is a document preparation system that is not similar to a word processor and is the gold standard for the typesetting of complex mathematical equations and symbols. LaTeX is accessible as free software and does not require any sort of payment to use the system.
This system is widely used in areas like mathematics, statistics, physics, etc. LaTeX can also prepare documents in multilingual languages such as Greek and Latin. The sigma symbol can be found in LaTeX by using the LaTeX commands. The command used for the uppercase sigma Σ is Sigma and the lower case sigma σ is sigma.
Sigma symbol for Instagram
Whenever a person needs to use special characters, symbols, or letters in their social media apps, they find it hard to come across such characters in their keypads because a large variety of these symbols or characters aren't installed in smartphones yet. If a user were to procure certain symbols or characters in his keypad, he'd probably obtain some of it by long-pressing certain keys like the $ which reveals a few other currencies along with it as well.

To obtain a symbol from this app, the user can search for the symbol, click on the symbol and copy it. Then he can go to Instagram, long press in the chatbox, or wherever he wants the sigma symbol to be and paste it.
What does Sigma Symbol mean in statistics?
The uppercase sigma Σ is used for the summation of a certain set of values. It is also referred to as sigma notation of a series. The formula in statistics tells us to sum up the function evaluated at particular points determined by the little numbers on top and below the big sigma and is used to add a particular series of numbers. Σ is also used to sum a function at specific points. ‘i' located at the bottom of the Σ symbol is the index and should have a starting value. The n located at the top of Σ is the variable. It can either be a variable or a number and is considered to be our ending value. is the element in the formula. In statistics, Σ can be used to signify the covariance matrix of a set of random variables.
The lower case sigma σ generally represents the standard deviation of a population. The formula σ = sqrt[ Σ ( Xi – μ )2 / N ] is used to calculate the standard deviation for a given population. In the formula sqrt is the square root, ‘Σ (Xi – μ)2' denotes a sum of squared deviations from their population mean, and N denotes the total population. The lower case sigma σ can also be used in normal distribution.
What does Sigma Symbol mean in physics?
In the field of physics, the uppercase sigma Σ and the lowercase sigma σ have a wide range of uses. Under the branch of condensed matter physics, uppercase Σ is used to denote the self-energy operator. Under the terminology of particle physics, uppercase Σ can be used to specify a class of baryons and under nuclear and particle physics, uppercase Σ is said to denote macroscopic cross-sections.
The lowercase sigma σ is used in physics to calculate the Pauli Matrices. In nuclear and particle physics, cross-sections are generally denoted by σ. The lowercase sigma σ is further used in areas like continuum mechanics to denote stress and astronomy to signify velocity dispersion. Under the terminology of electrostatics, the lower case sigma represents surface charge density. The lower case sigma σ also signifies factors like Stefan-Boltzmann constant in blackbody radiation, electrical conductivity, and area density in physics.
