hi, i have a performance utilization report that exports as an excel file. i have excel 2007. the excel file has two columns of data with column headers. the first column is time. the second column is cpu utilization. the time column cells are in 5 minute increments that include both the date and time for a period of one day. the second column has the cpu utilization statistic. i need to show a table with the high and low average of cpu utilization statistic for each hour. how can i use excel to do this?
