I'm trying to create a worksheet that calculates summary statistics (think mean and standard deviation) for the previous X timeframe (previous week, previous month, previous quarter, etc) dynamically, based on a cell for the start date.
I have it setup such that I had 2 columns of data; column A is the date for a given observation and column B is the number itself. I'd like to be able to type in a date to my date field and have my summary statistics automatically update.
Any help is appreciated! Thank you!
