grouping data together
Hi. i have a data, and there is 3 columns, Month, Year and Total. and there is over 1000 rows for them because there is 87 years data for every month, so there is month from Jan-Dec, and year from 1900-1987, so i was wondering if i would want to make 12 groups (Jan,Feb.......,Dec), and put each year's total into the corresponding month (so every month group will have 88 values of total) how
