For example, column A is number of days, Column B is a values, and column C is a % within values. There are 29 rows and I want to choose only one near or equals to 10% and 90% in B and day from A.
According to attached sheet my answer should be: A=156 and 254, B=44 and 77.
Is there any easy way to get this types of result in excel because I have 60 treatment plots, 29 observations, 8 different phenological phases for 30 species? (i.e.:52200 rows)
