Measurements are from each minut for each date. I want to have the max, min and average (lets say from temp.) from each day separately.
I have no idea how to do it. Have tried an IF function, but do not think i have done it right.
Hope there is someone who can help

Ps. the excel sheet is attached, in a shorter version.
