How to identify outliers values in DAX? Follow example bellow

Anonymous — Fri, 31 Mar 2023 21:00:25 GMT

Cod	Price	Outlier
300-0001-10	15000,00	Yes
300-0001-10	1,98	no
300-0001-10	2,00	no
300-0001-10	1,98	no
300-0002-11	1500	no
300-0002-11	1500	no
300-0002-11	0,01	yes

I need a DAX that show the outlier for each Cod number as example below. Second step is to show the status of the Outlier with "Yes" or "no". Thanks!

Anonymous not sure what is your criteria for the outlier of Cod number, is it the length of Cod column or min/max price for Cod column, also for the example data, there is no vertical line or space to seperate Cod and Price column, it is no possible to identify the data in both columns

Anonymous , seems you want to find the min and max of price, please see below measure and pbix file attached as well.

_outlier =

VAR _outlier_min = CALCULATE(MIN('Table'[Price]),all('Table'))

VAR _outlier_max = CALCULATE(MAX('Table'[Price]),all('Table'))

RETURN

IF(

CALCULATE(SUM('Table'[Price])) = _outlier_min || CALCULATE(SUM('Table'[Price])) = _outlier_max,

"Yes",

"No"

)

First of all, I'm glad you were so quick to help me.

Actually it would be the standard deviation I need. I put a few examples to facilitate understanding. To exemplify my need, imagine that in thousands of items, some items have very high or very low prices, but not all. So I need to find the standard deviation for the cases and delete them from the database.

here is a real example of my database, here we have two outliers, one with 216k and other 28k, both are outliers.

Anonymous , sorry, I am not sure what is your criteria for deviation, how do you define or measure the ourlier.

Maybe wait for other people to help. 😀

Hello! In the "cod."column I have two examples of the alot others: 300-0001-10 and 300-002-11. these two codes represent products with their respective prices and within each code I need to identify and show the Outliers. As the image bellow.
