AVEDEV(n1,n2,n3...)

• $n_{1},n_{2},n_{3}...$ are any real numbers.

Description

• AVEDEV returns the average of the absolute deviations of data points from its mean.
• Arguments can be numbers,names,arrays or references.

This function gives the average absolute deviation of a given set of numbers. The Average deviation is calculated in three steps:

1. We have to find the mean Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \bar{x}} .
2. To find the deviation of each value, subtract all numbers with its mean value.
3. Then find the average deviation, add all the deviation values and divide by the total number of given numbers.

Here we have to give more than one arguments. Arguments can be either number, name,logical values, arrays or cell references that contain numbers.

This function will give the result as error, when the text couldn't convert in to numbers.

• =AVEDEV(50,52, 54, 56, 58, 60) gives the result 3
  

Steps

1. Mean = Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \frac{50+52+ 54+ 56+ 58+ 60}{6} = \frac{330}{6} = 55}

• =AVEDEV(-20,40,-30,50,60) = 36
• =AVEDEV(-1.2,3.5,7,2,8.3,9.1) = 3.35
• =AVEDEV(B2:B5) = 1.75
