# Statistics for IT– Worldwideasy – 03

Statistics for it. Expanding the amount given in Sigma notation to a clear amount through this statistics lesson. Write a clear sum of S sigma notation. A clear pattern for individual terms. Using rules to handle money is expressed in Ig sigma notation. Explained.

## Sigma Notation for Statistics

• Sigma notation is a method used to write a long sum in a Short path.
• For example, we often like to summarize a number of terms 1 + 2 + 3 + 4 + 5 or a 1 + 4 + 9 + 16 + 25 + 36 There is a clear pattern to the numbers.
• More generally, we have u1, u2, u3,. . . , Otherwise we can write the sum of these numbers as u1 + u2 + u3 +. . . + un.
• This is an abbreviated form of writing that allows ur to represent the general term and put it in sequence.

See the Below example forget some idea.

## Writing a long sum in sigma notation – Statistics

Statistics – We have been given a long sum of money and suppose we want to declare. It is from Sigma numbering. How should we do this?

See below example,

## Rules for use with sigma notation

• In general, we can write if we add a constant n time.
• Suppose we have a fixed time collection.
• But from this calculation, we can see that the result is the same.
• Suppose we have the sum of k and a constant. Give us this.
• But from this calculation, we can see that the result is the same.
• If a and c are constants, and f (k) and g (k) are the functions of k.
