Study Notes
DAX Average Functions
- AVERAGE() function computes the average of the values contained in the provided column as input.
- A row is counted among the number of rows used as the divisor when a cell carries a value of 0, which is added to the sum of all the numbers.
- The row is not tallied when a cell is blank.
DAX AverageA Function
- AVERAGEA() function gives the average (arithmetic mean) of the values in a column.
- AVERAGEA function averages the values in a column and also manages non-numeric data types:
- Values that are TRUE, count as 1.
- Empty text (“”) counts as 0 (zero).
- Non-numeric text values have a count of 0 (zero).
- FALSE values are counted as 0 values (zero).
DAX AverageX Function
- AVERAGEX() function calculates the average (arithmetic mean) of a set of expressions evaluated over a table.
DAX Count Functions
- COUNT() function only accepts a column as an argument and counts the following types of values:
- Numbers
- Dates
- Strings
DAX CountA Function
- COUNTA() function determines how many rows in the chosen column have non-blank values.
- The function returns a blank if it cannot locate any rows to count.
DAX CountX Function
- COUNTX() function counts the number of rows that contain a number or an expression that evaluates to a number.
- It can be used to calculate the counts of rows based on certain expressions within FILTER.
- Requires two arguments: a table or an expression returning a table, and the column or expression that COUNTX searches for.
DAX CountAX Function
- COUNTAX() function counts non-blank results when evaluating the result of an expression over a table.
- It functions just like the COUNTA function but is used to loop across table rows and count the rows where the supplied expressions return a result that is not blank.
DAX CountBlank Function
- COUNTBLANK() function counts only blank cells in a column.
- Cells with the value zero (0) are not counted because zero is a valid numeric value and not a blank cell.
DAX CountRows Function
- COUNTROWS() function determines how many rows there are in the supplied table or a table that has been defined using an expression.
DAX DistinctCount Function
- DISTINCTCOUNT() function determines how many unique values there are in a column.
- It returns a BLANK if there are no rows to count; otherwise, it gives the number of distinct values.
- DISTINCTCOUNTNOBLANK() function also exists.
DAX MAX and MIN Functions
-
MAX() function returns the largest numeric value in a column or between two scalar expressions.
-
MAXA() function returns the largest value in a column, including any logical values and numbers represented as text.
-
MAXX() function evaluates an expression for each row of a table and returns the largest numeric value.
-
MIN() function returns the smallest numeric value in a column or between two scalar expressions.
-
MINA() function returns the smallest value in a column, including any logical values and numbers represented as text.
-
MINX() function returns the smallest numeric value that results from evaluating an expression for each row of a table.
DAX Product Functions
- PRODUCT() function returns the product of the numbers in a column.
- PRODUCTX() function returns the product of an expression evaluated for each row in a table.
DAX Sum Functions
- SUM() function adds all the numbers in a column.
- SUMX() function returns the sum of an expression evaluated for each row in a table.
