I have a spreadsheet with land prices per acre at different dates, expressed in the format mo/day/year. There are 66 items and the dates are NOT in order but are all in one column. I'd like to average the 2016, 2017, and 2018 prices separately. I think it can be done with an IF/THEN formula, but I don't know how to set it up! I have other attributes to analyze, but I think if you show me how to do this one I may be able to figure out the rest! Thanks!
