If you want to find the average of the last 3 non-zero values, you can use a combination of “AVERAGE”, “IF”, “ROW”, &” LARGE” functions to retrieve the output.
AVERAGE function can be used to find the average value or arithmetic mean of values in a selected range of cells.
number1, number2,……number n are numeric values.They can be numbers or names, arrays, of references that contain numbers.
The IF function checks if a condition you specify is TRUE or FALSE. If the condition returns TRUE then it returns preset value, and if the condition returns FALSE then it returns another preset value.
Syntax = IF(logical_test,value_if_true,value_if_false)
logical_test: Logical test will test the condition or criteria.If condition meets then it returns the preset value, and if the condition does not meet then it returnsanother preset value.
value_if_true: The value that you want to be returned if this argument returns TRUE.
value_if_false: The value that you want to be returned if this argument returns FALSE
ROW: Returns the row number of a reference.
Reference: It is a reference to a cell or range of cells.
LARGE: Returns the kth largest value in a data set. For example, the second largest number from a list of 10 items.
array: It is an array or range of cells in a list of data for which you want to find the kth largest value.
k: It is the kth position from largest value to return in the array or range of cells.
Let us take an example:
We have some numbers in column A.We want a formula that will give the average of last 3 non-zero values.
