Answer: sigma is used for measuring Population Standard Deviation.
Step-by-step explanation:
The lower case Greek letter 'sigma' is denoted by the symbol ( ).
This symbol indicates the Population Standard Deviation of the data. Standard deviation means how much variation or dispersion is there in our data. Squaring of standard deviation gives us Variance which is denoted by the symbol .
Formula for Population Standard deviation ( ) is = ,
where = each value from our list of data
= Population mean of data
N = Number of observations in our data
Standard deviation can never be negative and it is very much sensitive to outliers in our data.
Algebra is the study of operations, how an object is varied from a set of numbers. Moreover, calculus is the study of change among these numbers, the chain or algorithmic patterns of change or just random sets of change is the field that calculus values which algebra can not apply or understand. However with the application of both geometry and algebra, calculus is formed. It has the direction/shape and the set of operations at its disposal.
