In QGIS in the Attribute Table, I have a field with values.
For this field, I need to calculate the Sum of all its values and divide by the number of values that are not equal to "NULL"
.
Afterwards, I need to create a new field, where each value of the original field will be divided into the previously calculated (the Sum of all its values and divided by the number of values).
Is it possible to do this with the function editor in the Field Calculator (as this action will be repeated more than once)?
