AVERAGE()

• Parameters are any set of real numbers.
  • AVERAGE(), returns the average of its arguments.

Description

• This function gives the Average for given set numbers.
• Average means sum of all the given elements divided by Number of given elements.
• It is also called Arithmetic mean.
• i.e if $n$ numbers are given and each number is denoted by $a_{i}$, where $i=1$ to $n$, then

$A.M={\frac {1}{n}}\sum _{i=1}^{n}a_{i}$ = ${\frac {1}{n}}(a_{1}+a_{2}+.....+a_{n})$.

• In this function,the parameters can either be numbers,arrays,references of cells or we can enter the logical values directly.
• Arithmetic mean is the most common measures of central tendency.
• Central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data.
• The other common measures of central tendency are: Median,& Mode.
• A.M is calculated by adding the given set of numbers and divided by the count of the given set of numbers.

Average of 2,4,2,7,2,3 and 5 is 3.6

• Median: It is the middle number of a sorted list(Ascending order) of numbers.

The median of 2,2,2,3,4,5,7 is 3

• Mode: It is the most frequently repeated number in a given set of numbers.

The mode of 2,2,2,3,4,5 and 7 is 2.

• This function will show the result as Error,

1. when the values are error values or text that cannot change in to numbers.

ZOS

• The syntax is to calculate AVERAGE in ZOS is $AVERAGE()$.
  • Parameters are any set of real numbers.
• For e.g.,AVERAGE(10..15..0.25)
• AVERAGE(-10..-1)

Average

Examples

• AVERAGE( 2, 3, 11, 13, 17, 26, 34, 47) = 19.125
• AVERAGE(5,-2,7,8,11,20,25,-9) = 8.125
• AVG(2cm,200m) = 100.01m
• AVG(3kg,2000g,3000mg) = 1667666.6666666667mg
