# Sum function, divide cells containing data

counting for consistency.....

I would like to count using the Sum function but also divide by the number of cells that contain data.

Is this possible?

example:

Column A 1.0

Column B 5.0

Column C

Column D 4.0

Column E 2.0

Column F

=SUM 12.0)/4 = 3.0

Sum adding only cells that contain data, also string to be able to identify cells that have data and then divide by that number of cells.

Is this possible?
