average the 6 most recent dates
Column A has a list on various date entries, and column b has a list on numerical entries that correspond to the dates in column A.
I want to use a formula to average the most recent 6 entries (according to the date) in cell C1 and another formula to add
the most recent 6 entries (according to the date) in cell D1.
Is this possible? Thanks.
Anwsers to the Problem average the 6 most recent dates
what if I wanted to average the 30 most recent entries from column B by date with the same scenario already mentioned and also add the 30 most recent entries from column B by date ...
You can hard code the 30 into the formula as you mentioned or put it into a cell and reference the cell.
Let's assume that you put
30 into Z1.
Your two formulas would be,
You may want to tighten up those full column references (e.g.
A:A, B:B to
A2:A999, B2:B999) to save some processing power.
You can reference cells that are blank or contain text and they will be happily
skipped over byt the SUMIF() and AVERAGEIF() functions.
I've added a MIN(COUNT()) function to make sure that you are not asking for more values than are available.
- Open Internet Explorer.
- Go to "Tools > Internet Options > Advanced Tab".
- Uncheck "Enable third-party browser extensions".
- Click "Apply".
- Reboot your computer.
